Green yellow 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 33, 0, 88, 10.

The same color needs a different cmyk build depending on the paper. Here is #99e51b on both.

Coated stockgloss or silk, C

33 0 88 10

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

Uncoated stocknatural or matte, U

34 4 85 16

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 #99e51b is computed, not guessed. The rgb, hsl, hsv, cie-lab and xyz values follow the standard conversions from the sRGB color space. 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 figure is the nearest match in our reference set by perceptual distance and it is an approximation, not an exact spot color.
