Blue in print

The saturation is high, which is where rgb and cmyk drift apart, so a printed proof is worth it. The cmyk build is 71, 87, 0, 10.

The same color needs a different cmyk build depending on the paper. Here is #421de6 on both.

Coated stockgloss or silk, C

71 87 0 10

Ink sits on the surface, so colors stay bright and close to screen.

Uncoated stocknatural or matte, U

69 84 4 16

The stock absorbs ink and gains dot, so it needs a heavier build and reads a touch softer.

This color is saturated enough to sit near the edge of cmyk gamut, so expect a small drop in punch on paper and proof it before a long run.

How we calculate these values

The figures for #421de6 come from standard color math, shown so you can check them. Rgb, hsl, hsv, lab and xyz are derived through the usual sRGB conversion formulas. The coated and uncoated cmyk builds differ because uncoated stock absorbs more ink and gains dot, so the same color needs a heavier, slightly duller build on press. For Pantone we return the nearest reference by perceptual distance, which gets you close but is not a substitute for a physical swatch book.
