Slate gray is a moderate shade of gray with a slight azure tinge, which represents the average color of slate, a metamorphic rock often used in stonemasonry. As a tertiary color, slate is an equal mix of purple and green pigments.

Slaty, referring to this color, is often used to describe birds.

The first recorded use of slate gray as a color name in English was in 1705.
