How we calculate these values

The figures for #23368f come from standard color math, shown so you can check them. We convert from sRGB to each space with the standard formulas, so the codes match what design tools show. 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.
