The Oxford dictionary defines colour as “sensation produced on eye by rays of light when resolved as by prism into different wavelengths.” To simplify it, we may say that a colour is appearance of an object due to the rays of light. All colours are divided into three basic categories, primary, secondary and tertiary. Red, Blue and Yellow belong to former category and if you mix these colours in right proportion then we will get secondary colours. Similarly, if you will mix primary and secondary colours then the product will be a tertiary colour. The experts of this field have been working on their psychological implications and they have developed a theory on that. For instance, Red represents passion, emotion and excitement. Yellow carry the energy, modernism and optimism whereas orange is colour of warmness, friendliness and openness. Designers, painters and other visual artists keep these things in mind while creating a piece of art.
