Online color picker to view shades, tints, color codes, and complementary colors
A saturated, electric indigo, #3d40db sits dark on screen but reads loud thanks to its high chroma. Treat it as an accent or call-to-action color rather than a full background, where it can turn heavy. It flatters warm golds and ambers far more than safe grays. The hex code also clears WCAG AA with white text, hitting about 7.1:1 contrast.

When should #3d40db be used as an accent instead of a background?

Is #3d40db readable on white or black?
#3d40db has a 7.10:1 contrast ratio on white and 2.95:1 on black. WCAG asks for 4.5:1 for body text and 3:1 for large text, so on white it works for body text and on black it is too faint for text. Try other pairs in the contrast checker.
