How we calculate these values

Every value on this page for #355b9c is computed, not guessed. We convert from sRGB to each space with the standard formulas, so the codes match what design tools show. 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. The Pantone value is the closest reference by perceptual color distance and should be treated as a starting point, not a guaranteed match.
