#2A8B84 sits at 176° on the color wheel, placing it in the cyan family of the cool half of the spectrum. With 54% saturation and 35% lightness, it reads as a moderately saturated, shadowed tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 42, 139, 132 produces a 5.12:1 contrast ratio against black, which clears WCAG AA for body text in that pairing.
In RGB space #2A8B84 is a clear variant of CSS teal — about 44 units away from #008080. Designers reach for cyan 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.
