Cornflower 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 49, 44, 0, 2.

The same color needs a different cmyk build depending on the paper. Here is #818cfb on both.

Coated stockgloss or silk, C
49 44 0 2
Ink sits on the surface, so colors stay bright and close to screen.
Uncoated stocknatural or matte, U
49 44 4 8
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 #818cfb come from standard color math, shown so you can check them. The rgb, hsl, hsv, cie-lab and xyz values follow the standard conversions from the sRGB color space. 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.
