#91E3B0 sits at 143° on the color wheel, placing it in the spring green family of the cool half of the spectrum. With 59% saturation and 73% lightness, it reads as a moderately saturated, light tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 145, 227, 176 produces a 13.82:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #91E3B0 is a distant relative of CSS silver — about 61 units away from #C0C0C0. Designers reach for spring green 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.
