A shade made by adding black to a colour can be used for what?

Correct answer: Showing depth and shadow

Answer: A, showing depth and shadow. In basic colour theory, a shade is made by adding black to a colour. This lowers the lightness of the colour and produces a darker version. Artists can place darker shades on sides turned away from the light, inside recesses, beneath objects, or in areas that need to appear farther back. These dark areas help create depth and make a flat picture suggest volume. A is correct because darker values are useful for shadows and recession. B is wrong because adding black does not make a colour lighter; adding white produces a tint. C is wrong because bright highlights require lighter values, not a blackened shade. D is wrong because the purpose described here is darkening for value and form, not increasing saturation. The exact appearance can vary with the pigment, but the classroom distinction remains clear: shade means colour plus black, while tint means colour plus white. Memory cue: black takes light away, so shade helps show shadow and depth.
