#645CC2 sits at 245° on the color wheel, placing it in the blue family of the cool half of the spectrum. With 46% saturation and 56% 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, 92, 194 produces a 5.45:1 contrast ratio against white, which clears WCAG AA for body text in that pairing.
In RGB space #645CC2 is a close cousin of CSS slate blue — about 13 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.
