How we calculate these values

Here is how the numbers for #3f2a7a are worked out. Rgb, hsl, hsv, lab and xyz are derived through the usual sRGB conversion formulas. 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 figure is the nearest match in our reference set by perceptual distance and it is an approximation, not an exact spot color.
