#1F549E sits at 215° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 67% saturation and 37% lightness, it reads as a richly saturated, shadowed tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 31, 84, 158 produces a 7.45:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #1F549E is a distant relative of CSS teal — about 62 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.
