Dark slate 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 100, 66, 0, 23.

The same color needs a different cmyk build depending on the paper. Here is #0042c4 on both.

Coated stockgloss or silk, C

100 66 0 23

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

Uncoated stocknatural or matte, U

96 65 4 29

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

Here is how the numbers for #0042c4 are worked out. Rgb, hsl, hsv, lab and xyz are derived through the usual sRGB conversion formulas. The uncoated cmyk build carries more ink than the coated one, which is what a printer would compensate for when the same color runs on a rougher stock. The Pantone value is the closest reference by perceptual color distance and should be treated as a starting point, not a guaranteed match.
