#647AC7 sits at 227° on the color wheel, placing it in the blue family of the cool half of the spectrum. With 47% saturation and 59% lightness, it reads as a moderately saturated, light tone — a balanced mid-energy presence that sits comfortably alongside other UI tones. Its RGB mix of 100, 122, 199 produces a 5.15:1 contrast ratio against black, which clears WCAG AA for body text in that pairing.
In RGB space #647AC7 is a clear variant of CSS slate blue — about 33 units away from #6A5ACD. 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.
