#039A4A sits at 148° on the color wheel, placing it in the spring green family of the cool half of the spectrum. With 96% saturation and 31% lightness, it reads as a fully saturated, shadowed tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 3, 154, 74 produces a 5.72:1 contrast ratio against black, which clears WCAG AA for body text in that pairing.
In RGB space #039A4A is a clear variant of CSS sea green — about 47 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.
