#A6C9DF sits at 203° on the color wheel, placing it in the azure family of the cool half of the spectrum. With 47% saturation and 76% lightness, it reads as a moderately saturated, very light tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 166, 201, 223 produces a 12.04:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #A6C9DF is a clear variant of CSS sky blue — about 34 units away from #87CEEB. 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 lift, air, and gentle emphasis. On screen the cool cast tends to pair best with warm neutrals in the 25°-45° range to add life.
