#63747B sits at 198° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 11% saturation and 44% lightness, it reads as a heavily muted, shadowed tone — a quiet, restrained presence that recedes rather than competes. Its RGB mix of 99, 116, 123 produces a 4.87:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #63747B is a close cousin of CSS dim gray — about 22 units away from #696969. Designers reach for azure 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.
