When the Sienna Border for Grading

Psychology

Green at medium lightness is the colour of balance and renewal — neither as urgent as red nor as recessive as blue.

History

Scheele's Green, an arsenic-based pigment popular in Victorian wallpaper and clothing, is now understood to have caused widespread harm — a cautionary chapter in colour history.

Design use

At medium lightness, this green is flexible enough to serve as accent colours, call-to-action buttons, and icon fills — it holds its own without overwhelming adjacent elements. Always check WCAG contrast ratios before using it under or over text.

Colour pairings

In terms of colour combinations, for a natural palette, combine this green with terracotta, ochre, and warm cream. For a bolder approach, its complement — a warm red-magenta — creates immediate impact.
