#B5EC55 sits at 82° on the color wheel, placing it in the chartreuse family of the neutral half of the spectrum. With 80% saturation and 63% lightness, it reads as a richly saturated, light tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 181, 236, 85 produces a 15.09:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #B5EC55 is a clear variant of CSS yellow-green — about 54 units away from #9ACD32. Designers reach for chartreuse hues at this saturation when the brief calls for bold, immediate signal, and at this lightness when they want a present, comfortable mid-canvas voice. On screen the balanced cast tends to pair best with either warm or cool accents depending on the surrounding palette.
