Crimson

Because this red is extremely vivid, use it sparingly as a 10% accent for urgent calls to action or error states rather than as a background color. It is best reserved for elements that require immediate user attention.

Crimson pairs unexpectedly well with deep charcoal grays for a grounded, modern feel that prevents the red from feeling overwhelming. Neutral whites are also highly effective for text readability against this dark, saturated shade.
