Etymology

Origin of colour

C13: from Old French colour from Latin color tint, hue

Explanation

Red, black, lime green, hot pink — these are all examples of colours, or the different kinds of hues that objects have (spelled the British way). Imagine the colours of the rainbow or the colours in a box of crayons. But don't get thrown off by the spelling of this word for pigmentation. When Noah Webster was compiling his dictionary in 1828, he wanted to emphasize that the young United States spoke a different dialect than Britain. Colour with a "u" is a British spelling, and it was probably Webster who shortened it to color in America. Words like honour and flavour got the same treatment.
