#42C23D sits at 118° on the color wheel, placing it in the green family of the cool half of the spectrum. With 52% saturation and 50% lightness, it reads as a moderately saturated, balanced tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 66, 194, 61 produces a 9.02:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #42C23D is a distant relative of CSS sea green — about 64 units away from #2E8B57. Designers reach for green hues at this saturation when the brief calls for a conversational, mid-energy register, 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.
