#C3011B sits at 352° on the color wheel, placing it in the red family of the warm half of the spectrum. With 99% saturation and 38% lightness, it reads as a fully saturated, shadowed tone — an immediate, signal-grade voice that demands attention. Its RGB mix of 195, 1, 27 produces a 6.29:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #C3011B is a clear variant of CSS firebrick — about 38 units away from #B22222. 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.
