#12C25B sits at 145° on the color wheel, placing it in the spring green family of the cool half of the spectrum. With 83% saturation and 42% lightness, it reads as a richly saturated, shadowed tone — an immediate, signal-grade voice that demands attention. Its RGB mix of 18, 194, 91 produces a 8.89:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #12C25B is a distant relative of CSS sea green — about 62 units away from #2E8B57. 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.
