How we calculate these values

Every value on this page for #3390ac 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. For Pantone we return the nearest reference by perceptual distance, which gets you close but is not a substitute for a physical swatch book.
