Colour: One's perception of hue,
lightness/brightness and saturation.
Note: This is the British and Canadian way of spelling colour, therefore, the correct way. I realize that
American's think that they invented the English language (along with everything else)but they did not. The Brits or ENGLISH invented the language (where do you think the name came from?). Why do American's spell it color? Years ago when the first American dictionary was written, the person writing it was a horrible
speller.
