#B1F8EF sits at 172° on the color wheel, placing it in the cyan family of the cool half of the spectrum. With 84% saturation and 83% lightness, it reads as a richly saturated, very light tone — a soft but unmistakably tinted presence. Its RGB mix of 177, 248, 239 produces a 17.54:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #B1F8EF is a clear variant of CSS gainsboro — about 55 units away from #DCDCDC. Designers reach for cyan hues at this saturation when the brief calls for bold, immediate signal, and at this lightness when they want lift, air, and gentle emphasis. On screen the cool cast tends to pair best with warm neutrals in the 25°-45° range to add life.
