“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.”

— Jayant Narlikar

His observations on the "strange events in our solar system" and as to why the sky looked blue and red colour was used in traffic lights to signal to vehicles to stop.

“Colour-blindness always extends to the complementary colours. Those who are red blind are also green blind; those who are blind to blue have no consciousness of yellow. This law holds good for all mental phenomena; it is a fundamental condition of consciousness.”

“First: my Friend planted a Row of Indian corn that was Coloured Red and Blue; the rest of the Field being planted with corn of the yellow, which is the most usual color. To the Windward side, this Red and Blue Row, so infected Three or Four whole Rows, as to communicate the same Colour unto them; and part of ye Fifth and some of ye Sixth. But to the Leeward Side, no less than Seven or Eight Rows, had ye same Colour communicated unto them; and some small Impressions were made on those that were yet further off.”

As quoted in Zirkle, Conway (1935), The beginnings of plant hybridization p. 105

“Prospero wears a large, heavy, dark-blue cloak or gown that enfolds him like a quilted blanket… it is darkly embroidered with small wine-coloured beads and swirls of black vegetation… it has long strings and ornate tassels that trail to the ground… it is a garment that has often been worn… a little frayed and scuffed. Later it will be seen to be capable of changing colour… in seven stages comparable to the power of Prospero's magic… black, brown, dark blue, light blue, purple, dark red and fiery red… and to have a vivid lining embroidered with dazzling stars -- a lining that is only revealed in flashes as when a dark butterfly momentarily uncovers coloured underwings.”

“Neo-Impressionist method is an attempt is made to achieve the richness of the sunlight spectrum with all its tones. An orange that blends with yellow and red, a violet that tends toward red and blue, a green between blue and yellow are, with white the sole elements. Through mixture (in the eye of the observer) of these pure colours, whose relationship can be varied at will, from the most brilliant to the greyish. Every brush stroke that is taken from the palette remains pure on the canvas.”

Paul Signac (1863–1935) French painter

“Blue has no dimensions, it is beyond dimensions, whereas the other colours are not. They are pre-psychological expanses, red, for example, presupposing a site radiating heat... All colours arouse specific associative ideas, psychologically material or tangible, while blue suggests at most the sea and sky, and they, after all, are in actual, visible nature what is most abstract.”
