#A3F3C9 sits at 149° on the color wheel, placing it in the spring green family of the cool half of the spectrum. With 77% saturation and 80% lightness, it reads as a richly saturated, very light tone — a soft but unmistakably tinted presence. Its RGB mix of 163, 243, 201 produces a 16.22:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #A3F3C9 is a clear variant of CSS sky blue — about 58 units away from #87CEEB. Designers reach for spring green hues at this saturation when the brief calls for bold, immediate signal, 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.
