#2D4E81 sits at 216° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 48% saturation and 34% lightness, it reads as a moderately saturated, shadowed tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 45, 78, 129 produces a 8.34:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #2D4E81 is a distant relative of CSS teal — about 67 units away from #008080. 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 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.
