#645B7F sits at 255° on the color wheel, placing it in the violet family of the cool half of the spectrum. With 17% saturation and 43% lightness, it reads as a heavily muted, shadowed tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 100, 91, 127 produces a 6.28:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #645B7F is a clear variant of CSS dim gray — about 27 units away from #696969. Designers reach for violet hues at this saturation when the brief calls for restraint and atmosphere, and at this lightness when they want a present, comfortable mid-canvas voice. On screen the cool cast tends to pair best with warm neutrals in the 25°-45° range to add life.
