#187D7A sits at 178° on the color wheel, placing it in the cyan family of the cool half of the spectrum. With 68% saturation and 29% lightness, it reads as a richly saturated, shadowed tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 24, 125, 122 produces a 4.94:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #187D7A is a close cousin of CSS teal — about 25 units away from #008080. Designers reach for cyan hues at this saturation when the brief calls for a conversational, mid-energy register, and at this lightness when they want weight, depth, and grounded contrast. On screen the cool cast tends to pair best with warm neutrals in the 25°-45° range to add life.
