Description
Slate (#516572) is a medium, neutral gray with a cool-leaning neutral feel. It has a hue angle of 204° and a lightness of 50%. As a neutral it supports other colors rather than competing with them.
Psychology
Gray is neutral and composed. It recedes, which is why it is the workhorse of interfaces: borders, secondary text and surfaces that let accents stand out. As a mid-toned shade, Slate sits comfortably in the middle: present but not heavy.
Meaning
Gray suggests balance, restraint and professionalism, and sometimes dullness if nothing else adds life.
Why use this color
Slate is a flexible base. It carries white text well, so it works as a button, header or badge background. Pair it with its tints and shades for a complete scale.
Applications
- UI borders, text and surfaces
- Technology and architecture
- Minimal, balanced layouts
- Backdrops for accent colors
History
Gray is one of the oldest color words in English. Payne's gray is named after the eighteenth century watercolorist William Payne.
