What is the lighter form produced by adding white to acrylic colour called?

Correct answer: Tint

In colour theory, a tint is made by adding white to a base colour, increasing its lightness while retaining the basic hue. Thus, option C is correct. A shade is normally produced by adding black, and a line or texture describes a visual mark or surface quality rather than a lighter colour mixture. For example, red mixed with white becomes a lighter red tint. The amount of white controls the final value.
