#636F56 sits at 89° on the color wheel, placing it in the chartreuse family of the neutral half of the spectrum. With 13% saturation and 39% lightness, it reads as a heavily muted, shadowed tone — a quiet, restrained presence that recedes rather than competes. Its RGB mix of 99, 111, 86 produces a 5.33:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #636F56 is a close cousin of CSS dim gray — about 21 units away from #696969. Designers reach for chartreuse 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 balanced cast tends to pair best with either warm or cool accents depending on the surrounding palette.
