What colour is generally formed by adding white to red?

Correct answer: Pink

The governing concept is a tint: adding white to a hue produces a lighter version of that hue. Red mixed with white therefore gives pink or a light red, so option A is correct. The precise pink shade depends on the ratio; a small amount of white gives a deep pink, while more white gives a pale pink. Brown, green, and violet require different pigment combinations and are not the normal result of only red and white.
