#637F69 sits at 133° on the color wheel, placing it in the green family of the cool half of the spectrum. With 12% 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, 127, 105 produces a 4.77:1 contrast ratio against black, which clears WCAG AA for body text in that pairing.
In RGB space #637F69 is a close cousin of CSS dim gray — about 23 units away from #696969. Designers reach for green 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.
