How we calculate these values

Every value on this page for #40186b is computed, not guessed. 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.
