The rainbow colours, as we know them, are red, orange, yellow, green, blue, indigo, violet, but in reality, rainbows are a huge spectrum of chromatic hues.

Artists, designers and brands use this language to convey a desired reaction or message. This print is a guide to some of the symbolism and psychology of colours, the positive and the negative.
