Tint Colors are a type of named color. They are based on another named color (called the parent color) but with the addition of white, so any changes made to the parent color will be reflected in the tint. Use tints:

As a quick way to define new named colors. For example Pink could be defined as 50% Red.

To extend the range of colors available for printing inks. For example, a 75% black tint gives dark gray, a 25% black tint light gray. This gives three colors using just one ink.

To create highlights of the parent color.

A tint can be based on any other named color, including another tint.
