#5B857F sits at 171° on the color wheel, placing it in the cyan family of the cool half of the spectrum. With 19% saturation and 44% 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 91, 133, 127 produces a 5.11:1 contrast ratio against black, which clears WCAG AA for body text in that pairing.
In RGB space #5B857F is a clear variant of CSS gray — about 37 units away from #808080. Designers reach for cyan 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.
