What process is used to lighten a color by adding white?

The process of lightening a color by adding white is specifically referred to as a tint. When white is mixed with a color, it results in a lighter version of that color, creating a pastel hue. This is a fundamental concept in color theory, where the manipulation of colors through the addition of other pigments can drastically alter their appearance.

In the context of the other terms, shade refers to creating a darker version of a color by adding black. Tone involves altering a color by adding gray, which can either lighten or darken it depending on the ratio of black and white mixed with the original color. Value relates to the lightness or darkness of a color but does not specify the act of mixing with white or any other color. By understanding these distinctions, it's clear why the process of mixing white with a color to make it lighter is categorized as tinting.
