How we calculate these values

Every value on this page for #243b71 is computed, not guessed. Rgb, hsl, hsv, lab and xyz are derived through the usual sRGB conversion formulas. Two cmyk builds are shown because coated and uncoated papers behave differently, uncoated soaks up ink and needs more of it to hit the same target. The Pantone value is the closest reference by perceptual color distance and should be treated as a starting point, not a guaranteed match.
