How we calculate these values

Every value on this page for #4138a7 is computed, not guessed. Rgb, hsl, hsv, lab and xyz are derived through the usual sRGB conversion formulas. 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.
