#1F4B3A sits at 157° on the color wheel, placing it in the spring green family of the cool half of the spectrum. With 42% saturation and 21% lightness, it reads as a moderately saturated, deep tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 31, 75, 58 produces a 9.88:1 contrast ratio against white, which clears WCAG AAA for body text in that pairing.
In RGB space #1F4B3A is a distant relative of CSS forest green — about 68 units away from #228B22. Designers reach for spring green hues at this saturation when the brief calls for a conversational, mid-energy register, and at this lightness when they want weight, depth, and grounded contrast. On screen the cool cast tends to pair best with warm neutrals in the 25°-45° range to add life.
