#405C5F sits at 186° on the color wheel, placing it in the cyan family of the cool half of the spectrum. With 19% saturation and 31% 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 64, 92, 95 produces a 7.21:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #405C5F is a clear variant of CSS dim gray — about 44 units away from #696969. 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.
