Spring green 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 87, 0, 61, 0.

The same color needs a different cmyk build depending on the paper. Here is #21ff64 on both.

Coated stockgloss or silk, C

87 0 61 0

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

Uncoated stocknatural or matte, U

84 4 60 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

The figures for #21ff64 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. 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 value is the closest reference by perceptual color distance and should be treated as a starting point, not a guaranteed match.
