#377C8E sits at 192° on the color wheel, placing it in the cyan family of the cool half of the spectrum. With 44% saturation and 39% 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 55, 124, 142 produces a 4.73:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #377C8E is a clear variant of CSS steel blue — about 41 units away from #4682B4. 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.
