Coated stockgloss or silk, C
89 58 0 44
Ink sits on the surface, so colors stay bright and close to screen.
Uncoated stocknatural or matte, U
86 57 4 50
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 #103c8e 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. The uncoated cmyk build carries more ink than the coated one, which is what a printer would compensate for when the same color runs on a rougher stock. For Pantone we return the nearest reference by perceptual distance, which gets you close but is not a substitute for a physical swatch book.
