What is the most likely result of adding a small amount of black to primary blue?

Correct answer: Dark blue

Black reduces the lightness or value of a colour. When a small amount is mixed into primary blue, the result is normally a darker blue, called a shade of blue. White would create light blue or a tint, while green and violet require the addition of other hues rather than black alone. Thus, option B is correct. The word “small” also indicates a darkened blue rather than an entirely black mixture.
