What is the process of creating a darker form of a colour called?

Correct answer: Making a shade

The governing colour-theory concept is value change within a hue. A shade is a darker form of a colour, commonly created by adding a controlled amount of black. Option A is correct because it names this darkening process. A tint is the lighter form made with white, drawing a line is a mark-making action, and cutting paper is a craft process unrelated to changing colour value. Too much black should be avoided because it can overpower the hue.
