How we calculate these values

The figures for #673f91 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. 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. The Pantone figure is the nearest match in our reference set by perceptual distance and it is an approximation, not an exact spot color.
