#5B1B3B sits at 330° on the color wheel, placing it in the rose family of the warm half of the spectrum. With 54% saturation and 23% lightness, it reads as a moderately saturated, deep tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 91, 27, 59 produces a 12.61:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #5B1B3B is a distant relative of CSS maroon — about 75 units away from #800000. Designers reach for rose hues at this saturation when the brief calls for a conversational, mid-energy register, and at this lightness when they want weight, depth, and grounded contrast. On screen the warm cast tends to pair best with cool neutrals around 210°-230° to balance temperature.
