@squattingPigeon It seems I lent someone my copy of “Foundations of Color” and would not be able to get it back soon. May I review a different book on color instead?

Colours play very important roles in our everyday lives which could range from identifying and differentiating objects, to how we describe people and also having direct impact in our lives due to one or more previous experience(s). Have you ever wondered if we see colours the same way? Are you really convinced we see the same colours just as it is? Or can my blue be your purple? How does colour affect a person’s mood? Do we all associate red color with danger or black as evil? Since time immemorial, colours have been a very important part of our lives and have influenced generally the way we see or perceive people and objects. Colours can also represent our moods and how we feel towards a particular situation. For example, I feel more comfortable putting on dark coloured clothes or those with darker and dull shades which explains why I am introverted in nature unlike extremely flashy colours such as yellow, white, lemon which are bound to draw attention in public. Visual artists attach a whole lot of importance to colours which enables them create a piece where the colour(s) used will blend with the actual images to create a sense of meaning to the art work.

Colours play a major role in helping us make meaning of our immediate environment. This curiosity made me stumble upon several research publications that answered my questions.

Going through one of his publications titled, ‘Do different people see the same colours?’, Jabulani Sikhakhane opined that the brain plays a major role in determining how different people see colours and after carefully reading through, I agreed with the authors point of view where he argued that our brain also see just like our eyes would. He continued further by stating thus;” We say we see different colours because of how our brains learn to link the signals they get from the eyes with the names of different colours”. He also cited an example of when a baby points at a ball and her father asks, “would you like to play with that green ball?”, she learns to associate the colour she’s seeing with the word “green”, and she will soon call things of a similar colour “green” as well.

Going further with my research, I observed that our tendency to identify colours is directionally proportional to the amount of light or illumination that enters our eyes which helps us interpret these colours to make more sense of the image and I decided to find out.

I went strolling with a friend and we sat down at the center of a field close by. While we chatted, I noticed the sky was much more colourful than usual. I admired how different shades of blue were circled around each other and in a bid to express my satisfaction with what I considered a perfect piece of art, I asked James to tell me what colours he could find in the sky and he mentioned royal blue with white but I saw a lighter shade of blue and orange. I needed to know if truly we see colours just the same way or they appear the same way upon sight but differently in our inner eye?

I continued my research on how colours affects our perception and how they describe an artist’s work and also if these colours can truly connect with our reality. I can state that the importance of colours in representing or explaining a piece of artwork cannot be over emphasized as it gives meaning to every form of visual art. The use of colours to represent a scene helps art collectors select the best piece that directly represents how they feel about a particular subject or someone as the case may be.

Colours can be represented in different forms to produce a finished artwork which must agree with the situation being explained therein. Take for instance, an artist who wants to make a painting that has an agricultural theme or of farmers working out in the farm, it is very much important to consider the use of colours that represents agriculture or earth which easily would be all shades of green. The reason is because the lens in our eyes has adopted green as the primary colour representing nature and earth thereby creating a sense of reality in that artwork.


Going further, I stumbled upon an artwork created in 1885 by Vincent Van Gogh titled, ‘The Potato Eaters’ which he created by using oil on canvas. The image below describes a peasant family who are dependent on agriculture and land for survival. I admire the earthy green and brown colours he used in this piece which truly defined and added meaning to it. The essence of this was to connect reality with our imaginations by just sighting the art work.


The Potato Eaters, 1885 (oil on canvas)


I stumbled upon another piece of art by Pablo Picasso where he used blue to express his emotions in one of his most popular piece titled, ‘The Old Guitarist’. This artwork was inspired by the loss of his closest friend which led to his depression and decided to make a painting representing his mood. The painting was of an old man with twisted legs and a sad face holding on to a brown guitar with sad tones overwhelming the ambiance indicating the torments he was going through at that time. Blue signifies sadness and coolness which perfectly describes the reason behind its use. Understanding the use of colours to describe a situation has continued to give meaning to art and its collectors.


Colours are very important aspect of our lives and helps in the organization of events and people. The concept of colour is far more complicated than we think and the moment we begin to truly understand how colours are applicable in our everyday lives, and then we can begin to make more and better informed decisions which will be represented in our art.

Article; Colour Experience/perception.

Purpose/Target ;
To air personal view and perception of colours and educate.

What is colour?

Color or colour is the visual perceptual property corresponding in humans to the categories called red, blue, yellow, green, purple, white etc. Color derives from the spectrum of light interacting in the eye with the spectral sensitivities of the light receptors.

You can all agree with me that colour is a major part in human and the entire universe !
For sure, that’s because not a thing is colorless! Weather skin or non entity alike. This brings to the understanding of my existence that took me into findings about different colors and what they could possibly pose. Which now imbibed that color could imply different things to different persons based on their mood and sense of knowledge. It could tell a persons ideology or personality…

Vision is obviously involved in the perception of colour. A person can see in dim light, however, without being able to distinguish colours. Only when more light is present do colours appear. Light of some critical intensity, therefore, is also necessary for colour perception. Finally, the manner in which the brain responds to visual stimuli must also be considered. Even under identical conditions, the same object may appear red to one observer and orange to another. Clearly, the perception of colour depends on vision, light, and individual interpretation, and an understanding of colour involves many deep meaning.

The three additive primary colours are red, green, and blue; this means that, by additively mixing the colours red, green, and blue in varying amounts, almost all other colours can be produced, and, when the three primaries are added together in equal amounts, white is produced.

Colour can can be of great importance and use to artists, it can help in telling their story more and in the choice of color of an artist one can easily relate to the message being passed and that will enable for more details on the very article.


• Different colors evoke different emotions: yes! That’s the reason you see people favorite red as stands for love and wonder why it’s also used for danger?

• You’re more likely to forget something when it’s in black and white: well, that’s a fact.

• Men and women see colors differently: that can be also dependent on how certain beliefs of men and women differ.
• Blue is the world’s favorite color.

Sooooo, I’ll going to try my best to share a bit of my perspective. I ask for a bit of forgiveness from the crowd, perspective is hard to get across in a message :smiley:

Take as much, or as little from this as you like.

If I might, I would like to start with a story…

A young lad walks out of school, thinking maths/sciences are stupid. He passes all his classes, but never really learns anything. Feeling as though it’s all figured out already, thinking they are painfully boring, and he thinks little of those worlds. It must be the brainiacs that find the joy in understand these things :stuck_out_tongue:

This story is a tragedy… because they’re both F–kin awesome!

Color is also, F’n awesome.

So, why?

It’s one of the few tools, that lets you play in the world of feels. The only thing that’s comparable is musical notes (C,D, Major, Minors etc).

So, how do I use color?

We play with it. Say we start arting, right here, right now! We have the intent to make ourselves feel a bit sad. So, that’s what we will be trying to capture.

What makes us sad? Does a bright sunny day, make us sad?


What about a bunch-O really bright primary colors, just exploding all over the place???

Well that makes me feel like I’m at a party, so no.

Okay then, lets go the opposite way! Dark, and muddy?

Better, but the type of sad we’re after tonight is something like dropping your fav sandwich… on the sidewalk… right as your about to take the first bite… you know it’s gone forever…

I hope you can understand why we can’t just go with dark and muddy colors here, it’s just not the right feels. Think streets you’ve been on before, that’s our background color. Let us juxtapose that, against all the vibrant colors of the mouth watering sandwich innards. We’re drawing focus towards the crime scene. Then we need to think about the lighting.

What time of the day would you crave the perfect sandwich? Like REALLY crave a good sandwich. none of this “of ever day at 6” crap. It has to be THAT day. Not the worst day ever, but just one of those days. Maybe at the end of a long day, working hard on something I don’t really enjoy doing. or worse? you chose.

What about Twilight lighting? It can be very moody?

Ya, but this is not about a beautiful sunset, it’s about the sorrow of a lost friend, who deserved a better ending. So it’s just dark out, and your just looking down at the concrete sidewalk. The only light is cast from dim street light. No real moon out tonight. So it becomes a bluey-purpleish-grey background, with the crazy red’s of the tomatoes and greens of the veg. All muted out by that weird yellow light. A sad song plays from a radio close by. RIP BLT.

We just happen to have landed on a perfect yellow/orange/blue/purple color palette. How? There was no plan for that?!?!


Don’t try to follow all the rules, just follow feelings. To really wield color, you go by feel. Put something down, ask how you feel about it, repeat.

I’ve read, listened, and generally stewed in a lot of information about color theory, for years now ><. I’ve used little of what I’ve learned. Some technical information about color has been cool. For instance, if you’ve ever seen sunlight hit a colored wall. You may have noticed how much that walls color fills the room. Or you might be curious how matte colors, vs shiney colors work (Hint it has to do with the objects surface rough/smoothness). There’s lots of fun to be had discovering all the odd things that make things look like things, but you don’t need to stress about them, they’re more like curiosities.

I hope this helps,

The red color at the nature

Red. One of the primarie colors, along with blue and yellow. As a light, red is also a primary, with blue and green.

Theres a missunderstanding about the red color over society along the years. Red at natural biomes, mostly of the time, its a color related to problem.

It is also associated to danger, blood, luxury, desire, attraction, romance, lust, anger, hungry, as at the same time, theres some places that name it for happiness, fortune, richness and joy.

The first thing that came from the red its when I think about it, it the first sunlights that reachs the top of the trees and theres a gold red moment at the sky, for a few seconds. Its called the golden hour at someplaces. And its all about the red painting the begining of the day.

The long wavelenght, 625 a 740 nm, makes it the most perceptual lightwave from the human perspective, making it easy to be distinguish from any other color. Maybe this is the motive that society treated the red color so unacurated. Because its stimulates our vision and brain so much, that was associated to extreme things. The stop sign. Alerts. And the cardinals vests, the cars, luxury itens, food places, blood and violence. Even the green Incredible Hulk. It is all about the red color.

The red its next to orange and opposite to violet.

Most primates can see the full spectrum of colors, but its not the case for many other mammals. They can distinguish blue, yellow, but green and red are seen as a gray.
Bulls cant see the red either.

Bellow the red frequency and wavelenght its called infrared and its perceive by humans only as the form of heat.

Red is a powerful color. Brands use it and even have the rights for their red color. Theres the ferrari red, the coke red, and so on.

And theres the red into nature.

Most of the red manifestation at nature are popular associated with danger but thats not a rule. At Mata Atlantica, south america biome, the richiest ecosystem by species, the red color appears mostly as the opposite. They are used to claim atention. The red is easily been seen into the green areas. The palmito trees have a red visible root, the tangará bird have a red spot at the top of their heads, contrasting with their cyan and black body plumes. There are seeds, flowers, branches, animals, red, from scarlet to dark ones, all of them claiming for us and every other species to see them. “Eat me” or “watch my performance”, “I’m not afraid and you should not be either”, they are saying somehow. Of course this should not to be used as a guide to survival, or to eat every red thing at the forest, even touch every red plant. Dont do it. There are dangers also. Letal ones too. The armadeira spider is considered to have the most painful spider bite ever, and you can see that at the scarlet fangs under those eyesights. Beware.

The iron color came from oxydes of iron or aluminum. So you can be certain to see red colored spots when you go for a walk into the deep green tropical forest.

The constrast of the red into the green and brown enviroment appears to us as a post-impressionist dream. It pops up, and at the same time its so different from everything around, its so rare, that you can spot it from a huge distance. A tiê-sangue, a deep scarlet to red bright bird, its so different from the enviroment, that you can see that its not trying to hide from predators, at all.

The flora, or the plants, goes the same way. The reddish of the leaves are related to the anthocyanins. They are produced at larger scales when the sun light is more intense. Red leaves to the sun, dark green ones to the shade.

At the boards of the forest, the biome mix it up with a country side enviroment, full of reddish elements also. Theres a small wild fruit, know by Bitter Melon, that have extreme red seeds, thats it know by the old people to cure poison, and its healthy to eat. Theres usage of it at chinese food recipes. The mature version of the fruit is a sweet reddish full of proteins and essential amino acids.

Also theres the coral snake. Red as a ruby, deadly and mortal. But theres the yellow and orange mixed into the snake’s texture. Also theres a small bush around, with a yellow-orange beautifull fruit. Poisonous. The dark and blue colors came from the same mix that makes things red. Blueberries, jaboticabas, even small wild berries, beans, all dark healthy ones. The venomous wasps? Yellow ones. But theres the bananas, papayas, maracujas, cajus, all yellow and orange. So theres no rule, at least not that a study, for the danger of the yellow at nature. But they are all around, with frogs, plants, deadly poisonous yellow stuff.
