#637E5C sits at 108° on the color wheel, placing it in the green family of the cool half of the spectrum. With 16% 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 99, 126, 92 produces a 4.67:1 contrast ratio against black, which clears WCAG AA for body text in that pairing.
In RGB space #637E5C is a clear variant of CSS dim gray — about 25 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.
