Dark slate blue in print

A color this vivid sometimes sits just outside cmyk gamut, so expect a small dip in punch on paper. The cmyk build is 94, 67, 0, 28.

The same color needs a different cmyk build depending on the paper. Here is #0b3db8 on both.

Coated stockgloss or silk, C

94 67 0 28

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

Uncoated stocknatural or matte, U

90 66 4 34

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 #0b3db8 are worked out. Rgb, hsl, hsv, lab and xyz are derived through the usual sRGB conversion formulas. Two cmyk builds are shown because coated and uncoated papers behave differently, uncoated soaks up ink and needs more of it to hit the same target. The Pantone figure is the nearest match in our reference set by perceptual distance and it is an approximation, not an exact spot color.
