How do I use blue and orange 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.
