#421F6E sits at 267° on the color wheel, placing it in the violet family of the cool half of the spectrum. With 56% saturation and 28% 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 66, 31, 110 produces a 12.71:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #421F6E is a clear variant of CSS indigo — about 38 units away from #4B0082. Designers reach for violet 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 cool cast tends to pair best with warm neutrals in the 25°-45° range to add life.
