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 89, 68, 0, 29.

The same color needs a different cmyk build depending on the paper. Here is #143ab4 on both.

Coated stockgloss or silk, C

89 68 0 29

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

Uncoated stocknatural or matte, U

86 67 4 35

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 #143ab4 is computed, not guessed. We convert from sRGB to each space with the standard formulas, so the codes match what design tools show. 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. The Pantone value is the closest reference by perceptual color distance and should be treated as a starting point, not a guaranteed match.
