We have seven colours - violet, indigo, blue, green, yellow, orange and red (Roy G. Biv). Our atmosphere has a number of particles and when light falls on them, it gets scattered. With blue colour having less wavelength and more scattering qualities, it scatters and makes the sky blue. While red colour has opposite qualities than blue so traffic lights are of this colour.

The Bayeux Tapestry is accepted as an authority on many details of life and the fine points of history in the eleventh century. For instance, the horses in those days had green legs, blue bodies, yellow manes, and red heads, while the people were all double-jointed and quite different from what we generally think of as human beings.

pinkish and bluish draperies on neutral grey grounds and black cypresses... ...The red of Jeptha's dress... ...some reddish brown, some slightly pinkish... ...Graduated blue sky... ...the ground at the front a grey violet shadow... Look for some turquoise in the blue.(Degas' working note about choosing colors for his future painting 'The Daughter of Jeptha')
Edgar Degas
I wish I had the talent to paint the way I feel about you, for my words always feel inadequate. I imagine using red for your passion and pale blue for your kindness; forest green to reflect the depth of your empathy and bright yellow for your unflagging optimism. And still I wonder: can even an artist's palette capture the full range of what you mean to me?
Nicholas Sparks
Colour, if I may say so, is biological. Colour is alive and colour alone makes things come alive... Without losing any part of myself, I need to get back to that instinct, so that these colours in the scattered fields signify an idea to me, just as to them they signify a crop. Confronted by a yellow, they spontaneously feel the harvesting activity required of them, just as I, when faced with the same ripening tint..
Paul Cézanne
In 1942 when I was in New York, I was struck by the neon advertisements flashing all over Broadway. You are there, you talk to someone, and all of a sudden he turns blue. Then the colour fades - another one comes and turns him red or yellow. The colour – the colour of neon advertising is free; it exists in space. I wanted to do the same in my canvases.
