#02838D sits at 184° on the color wheel, placing it in the cyan family of the cool half of the spectrum. With 97% saturation and 28% lightness, it reads as a fully saturated, shadowed tone — a weighted, dramatic presence with deep undertones. Its RGB mix of 2, 131, 141 produces a 4.63:1 contrast ratio against black, which clears WCAG AA for body text in that pairing.
In RGB space #02838D is a close cousin of CSS teal — about 13 units away from #008080. Designers reach for cyan hues at this saturation when the brief calls for bold, immediate signal, 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.
