#C81E3A sits at 350° on the color wheel, placing it in the red family of the warm half of the spectrum. With 74% saturation and 45% lightness, it reads as a richly saturated, balanced tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 200, 30, 58 produces a 5.67:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #C81E3A is a close cousin of CSS crimson — about 22 units away from #DC143C. Designers reach for red hues at this saturation when the brief calls for bold, immediate signal, and at this lightness when they want a present, comfortable mid-canvas voice. On screen the warm cast tends to pair best with cool neutrals around 210°-230° to balance temperature.
