#15C6C6 sits at 180° on the color wheel, placing it in the cyan family of the cool half of the spectrum. With 81% saturation and 43% lightness, it reads as a richly saturated, shadowed tone — an immediate, signal-grade voice that demands attention. Its RGB mix of 21, 198, 198 produces a 9.92:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #15C6C6 is a clear variant of CSS turquoise — about 51 units away from #40E0D0. Designers reach for cyan hues at this saturation when the brief calls for bold, immediate signal, 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.
