#2B3F41 sits at 185° on the color wheel, placing it in the cyan family of the cool half of the spectrum. With 20% saturation and 21% lightness, it reads as a softly muted, deep tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 43, 63, 65 produces a 11.11:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #2B3F41 is a distant relative of CSS sea green — about 79 units away from #2E8B57. Designers reach for cyan hues at this saturation when the brief calls for restraint and atmosphere, 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.
