Not to be too persnicketty, but "colour" isn't used by artists etc. "Colour" is a vague generic term.

The term is "hue" which refers to a colour's place on the colour wheel.

"Tint" is the amount of white, "Shade" is the amount of black.

Another term is "saturation".

Here's one of many sites which discuss these terms. Artists need such terminology in order to discuss colours in a technical and specific manner
