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. Since these are complementary colors, lean toward a 70/25/5 split to keep the contrast from becoming overwhelming. Test the result with our Contrast Checker if text is involved.
