#37BF15 sits at 108° on the color wheel, placing it in the green family of the cool half of the spectrum. With 80% saturation and 42% lightness, it reads as a richly saturated, shadowed tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 55, 191, 21 produces a 8.63:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #37BF15 is a clear variant of CSS forest green — about 58 units away from #228B22. Designers reach for 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.
