How we calculate these values

Every value on this page for #343666 is computed, not guessed. 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 value is the closest reference by perceptual color distance and should be treated as a starting point, not a guaranteed match.
