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 61, 70, 0, 0.

The same color needs a different cmyk build depending on the paper. Here is #644bfe on both.

Coated stockgloss or silk, C
61 70 0 0
Ink sits on the surface, so colors stay bright and close to screen.
Uncoated stocknatural or matte, U
60 68 4 6
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

Every value on this page for #644bfe is computed, not guessed. The rgb, hsl, hsv, cie-lab and xyz values follow the standard conversions from the sRGB color space. 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. For Pantone we return the nearest reference by perceptual distance, which gets you close but is not a substitute for a physical swatch book.
