#687CBA sits at 225° on the color wheel, placing it in the blue family of the cool half of the spectrum. With 37% saturation and 57% lightness, it reads as a softly muted, light tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 104, 124, 186 produces a 5.18:1 contrast ratio against black, which clears WCAG AA for body text in that pairing.
In RGB space #687CBA is a clear variant of CSS steel blue — about 35 units away from #4682B4. Designers reach for blue 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.
