What is the color of sunlight?
Sunlight is not white, though it does contain a quantity of every colour we can see. What we perceive as colour depends on many things and is quite subjective. In one context the same object can appear (for example) yellow, green, grey or white. However if we ignore the subjective experience of colour, we can measure the colour of light objectively. One of the systems we use to measure colour is by comparing the relative strengths of the red, blue and green components of light. (These are the only colours we can actually see; all colours are described by our eyes to our brains in these terms.) White light would have equal components of red, green and blue, but sunlight does not.
