Do blue and brown go together?

Triadic schemes work best when one color dominates and the other two act as accents. The pairing has a WCAG contrast ratio of 1.21:1, which is below the AA threshold for text — use it for decorative purposes rather than text readability.

How do I use blue and brown in design?

A safe starting point is the 60/30/10 rule: give one color about 60 percent of the surface area, the other about 30 percent, and reserve the remaining 10 percent for an accent or neutral. If one color is significantly darker, use it for text or structural elements and the lighter one for backgrounds. Test the result with our Contrast Checker if text is involved.
