#2D5F5F sits at 180° on the color wheel, placing it in the cyan family of the cool half of the spectrum. With 36% saturation and 27% lightness, it reads as a softly muted, shadowed tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 45, 95, 95 produces a 7.21:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #2D5F5F is a clear variant of CSS sea green — about 45 units away from #2E8B57. 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.
