Colour is the visual perceptual property corresponding in humans to the categories called red, yellow, white, etc. Colour derives from the spectrum of light (distribution of light energy versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Colour categories and physical specifications of colour are also associated with objects, materials, light sources, etc., based on their physical properties such as light absorption, reflection, or emission spectra. In painting we have pigments, which is different than coloured light.
There are different colour theories, colour wheels.

Tree colour groups
- The primary colours Red, Yellow and Blue
- The secondary colours Green, Orange and Voile which are mixtures of the two primaries they sit between.
- The tertiary colours between yellow and orange, for example, is yellow orange, between blue and violet is blue violet and so on.
All these colours around the outside of the colour wheel are called saturated colours. They contain no black, no white and none of their complimentary or opposite colour.
Compound colours are colours containing a mixture of the three primaries. All the browns, khakis and earth colours are compound colours.
Hue red, yellow, green, blue or purple, colour we see
Lightness light vs. dark, or white vs. black
Saturation intense vs. dull, white or black or grey in the colour, achromatic
Contrast the primary colour gives the most strong colour contrast, very hard and noisy.
There are 5 different colour contrast and 4 other contrast
What we can use to change a spacious feel in a painting
1. Colour contrast
Colour to colour, hue to hue, contrast is always in a painting.
2. Complementary contrast
Colour who are opposite in the colour circle are the complementary colour, if you mix them you will get a kind of grey. This kinds of grey we will use this a lot in painting. Complementary contrast is the strongest contrast and will be used a lot in advertisements from cheap brands, because you see complimentary contrast very clear.
Complementary pigments and colours
For making grey out of complementary colour I use this wheel because painting pigments are not only pure hue.
In part this is because greys are especially susceptible to show the complementary colours induced by a contrasting surround colour, augmenting a colour effect: next to a bright red couch, a grey wall will appear distinctly greenish.
A blue colour with a small grey colour on it will get a simultaan contrast. Your eye will change the grey colour into a complementary colour, so for this blue it will be yellow. If you ever stand for the Boogie- woogie painting from Mondriaan for a long time, the painting will change colours.
3. Tonal contrast
Tonal contrast is simply the difference between the light and dark areas in a painting. The greater the difference the more attention the area attracts.
In the example above the eye goes straight to the area of contrast between the white and black shapes. When the tonal range is reduced, as in the second example, the eye still goes to the area of maximum contrast, but the design looses impact. Tonal contrast is one of the most powerful tools we have to define the centre of interest in a painting.
4. Saturation contrast, achromatic contrast
A colour wheel with achromatic colours.
Colour who have more white or black in it
Any colour that lacks strong chromatic content is said to be unsaturated, achromatic, or near neutral. Pure achromatic colours include black, white and all greys; near neutrals include browns, tans, pastels and dark side. Near neutrals can be either warm or cool.
Neutrals are obtained by mixing pure colours with either white or black, or by mixing two complementary colours. Red against soft old red.
Black and white dull the colour down.
5. Warm- cool contrast
The distinction between warm vs. cool colours has been important to painters since at least the late 18th century but is generally not remarked in modern colour science or colorimetric. The contrast, as traced by etymologies in the Oxford English Dictionary, seems related to the observed contrast in landscape light, between the “warm” colours of daylight or sunset and the “cool” colours of a grey or overcast day. Warm colours are hues from red through yellow, browns and tans included; cool colours are the hues from blue green through blue violet, most greys included.
Colour theory has ascribed perceptual and psychotically effects to this contrast. Warm colours are said to advance or appear more active in a painting, while cool colours tend to recede; used in interior design or fashion, warm colours are said to arouse or stimulate the viewer, while cool colours calm and relax.
Red warm comes forward, blue cold go’s back wards
Baris by Noella Roos
Most artist start in there live with big contrast’s and by getting older the contrast’s become more gentle, example Rembrandt started way more colourful in his live.
