How we calculate these values

Here is how the numbers for #6166ba are worked out. 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. For Pantone we return the nearest reference by perceptual distance, which gets you close but is not a substitute for a physical swatch book.
