#01B0CB sits at 188° on the color wheel, placing it in the cyan family of the cool half of the spectrum. With 99% saturation and 40% lightness, it reads as a fully saturated, shadowed tone — an immediate, signal-grade voice that demands attention. Its RGB mix of 1, 176, 203 produces a 8.07:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #01B0CB is a distant relative of CSS turquoise — about 79 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.
