How we calculate these values

Every value on this page for #283f48 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. For Pantone we return the nearest reference by perceptual distance, which gets you close but is not a substitute for a physical swatch book.
