#3EFFEC Hex Color

#3effec pairs well with charcoal and deep navy, which ground its bright teal presence and can provide strong contrast for text, controls, and accent-focused layouts without muting its crisp green undertone. White works better as surrounding space than as text over #3effec, where contrast is weak.

#3effec reads as a cool color because its cyan-teal base carries a clear green-blue bias rather than yellow or red warmth, giving it a crisp, energetic presence beside dark neutrals and cool-toned palettes. Its high saturation can feel almost neon in large areas.

#3effec provides strong contrast with black text, at roughly 16.7:1, exceeding WCAG AA and AAA thresholds for normal body text and large text, while making dark-on-light interface layouts especially practical. White text has very low contrast on #3effec, so use dark text instead.
