#91F81B sits at 88° on the color wheel, placing it in the chartreuse family of the neutral half of the spectrum. With 94% saturation and 54% lightness, it reads as a fully saturated, balanced tone — an immediate, signal-grade voice that demands attention. Its RGB mix of 145, 248, 27 produces a 15.65:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #91F81B is a clear variant of CSS lawn green — about 34 units away from #7CFC00. 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.
