#2B4B5B sits at 200° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 36% saturation and 26% 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 43, 75, 91 produces a 9.29:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #2B4B5B is a distant relative of CSS sea green — about 64 units away from #2E8B57. Designers reach for azure 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.
