1. The colour

2. 1. What is the colour?
Colour is LIGHT, broken down into wave lengths; each one has a different vibratory rate.

3. 2. Newton Experiment
YouTube - *The Visible Spectrum*

4. 3. Colour perception
● An object that absorbs all the light waves with no reflection back is perceived as black .
● One that reflects all the light is seen as white.
● We see an object as blue when the sunlight hits it and it absorbs all the colours of the spectrum except blue, which is reflected back.

5. Example
In this example you can check that you can perceive colours in a different way depending on the light and on the colours around it

6. 4. Additive mixture
If we mix light, we call it additive mixture

7. 5. Subtractive mixture
If we mix colours or pigments, we call it subtractive mixture

8. 6. Primary colours ● lemon yellow ● Magenta ● cyan
They’re the colours you can´t get with the mixture of any colour.

9. 7. Secondary colours
● yellow + magenta= red
● cyan + magenta=purple
● Cyan + yellow= green
When you mix two primary colours you get secondary colours.

10. 8. Tertiary colours
Here you can see combinations of primary and secondary colours.

11. Tertiary colours ●GREEN + RED = YELLOW GREY
●GREEN + PURPLE = BLUE GREY
●RED + PURPLE = PINK GREY

12. 9. Warm colours
Warm colors are often said to be hues from red through yellow, browns and tans included.

13. 10. Cool colours
Cool colors are often said to be the hues from blue green through blue violet.

15. 11. Neutral colours ●White ●Black ● Neutral Grey
They are the colours which aren’t warm or cool.

16. 12. Complementary colours
They are those colours which are opposite each other in the colour circle.

17. 13. Colour qualities ● Hue ● Saturation ● Value Darkness Lightness

18. 14. Colour scales ● Hue scales ●Saturation scales ●Value scales
 Tints (with white)
 Shadows (with black)

19. 15. Chromatic organization
We organize colours in different ways:

20. 16. Goethe triangle

21. 17. Colour wheel
● See also Color wheel - Wikipedia, the free encyclopedia

22. 18. Harmony
…Are the colours which have similar hues and are near in the colour wheel.

23. 19. Contrast
Contrast colours are those which have the opposite hue in the colour wheel.
