How we calculate these values

Here is how the numbers for #566c79 are worked out. We convert from sRGB to each space with the standard formulas, so the codes match what design tools show. 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. For Pantone we return the nearest reference by perceptual distance, which gets you close but is not a substitute for a physical swatch book.
