#B41D31 sits at 352° on the color wheel, placing it in the red family of the warm half of the spectrum. With 72% saturation and 41% lightness, it reads as a richly saturated, shadowed tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 180, 29, 49 produces a 6.64:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #B41D31 is a close cousin of CSS firebrick — about 16 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.
