What Frank Border via Measuring

Psychology

Yellow stimulates attention and optimism; at medium lightness it is highly visible and hard to ignore.

History

Yellow ochre is one of the oldest pigments known — used in the Lascaux cave paintings over 17,000 years ago, it remains a staple of artists' palettes today.

Design use

This shade sits in a versatile middle ground — useful as interactive elements, tags, badges, and highlight states. It has enough saturation to register clearly without straining extended-reading contexts.

Colour pairings

When it comes to colour harmony, combine this yellow with deep indigo for high-contrast drama, or with dusty sage and off-white for a palette of sunlit calm.
