#1BF869 sits at 141° on the color wheel, placing it in the spring green family of the cool 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 27, 248, 105 produces a 14.68:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #1BF869 is a clear variant of CSS medium spring green — about 56 units away from #00FA9A. Designers reach for spring green 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 cool cast tends to pair best with warm neutrals in the 25°-45° range to add life.
