#81F97E sits at 119° on the color wheel, placing it in the green family of the cool half of the spectrum. With 91% saturation and 74% lightness, it reads as a fully saturated, light tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 129, 249, 126 produces a 15.78:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #81F97E is a distant relative of CSS yellow-green — about 91 units away from #9ACD32. Designers reach for 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.
