#23B1D1 sits at 191° on the color wheel, placing it in the cyan family of the cool half of the spectrum. With 71% saturation and 48% lightness, it reads as a richly saturated, balanced tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 35, 177, 209 produces a 8.28:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #23B1D1 is a clear variant of CSS turquoise — about 55 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.
