Description

Oil (#313330) is a dark, neutral gray with a true neutral feel. It has a hue angle of 100° and a lightness of 32%. 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 dark shade, Oil feels weighty and serious.

Meaning

Gray suggests balance, restraint and professionalism, and sometimes dullness if nothing else adds life.

Why use this color

Oil 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.
