#C8102C sits at 351° on the color wheel, placing it in the red family of the warm half of the spectrum. With 85% saturation and 42% lightness, it reads as a fully saturated, shadowed tone — an immediate, signal-grade voice that demands attention. Its RGB mix of 200, 16, 44 produces a 5.89:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #C8102C is a clear variant of CSS crimson — about 26 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.
