#A33940 sits at 356° on the color wheel, placing it in the red family of the warm half of the spectrum. With 48% saturation and 43% lightness, it reads as a moderately saturated, shadowed tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 163, 57, 64 produces a 6.53:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #A33940 is a clear variant of CSS brown — about 27 units away from #A52A2A. Designers reach for red hues at this saturation when the brief calls for a conversational, mid-energy register, 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.
