What the Border between Lean Changing

Psychology

Orange is the colour of creativity and enthusiasm — stimulating without the urgency of red.

History

Dutch orange — the colour of the House of Nassau — became a national symbol through the Dutch Golden Age, a tradition that persists in football strips and celebration today.

Design use

At medium lightness, this orange 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, pair this orange with deep teal for bold contrast, or with warm sand and burnt umber for a palette that feels natural and grounded.
