Brex colors

Brex's 5 brand colors as structured tokens — every role's hex with copy buttons, contrast pairs measured against the brand's own surface, and CSS / DTCG downloads. Ask your agent for a palette inspired by Brex via the colors MCP.

Measured against the brand's own surface where it has one; fixes move lightness only so they stay on-hue.
