How we calculate these values

Here is how the numbers for #331fbc are worked out. The rgb, hsl, hsv, cie-lab and xyz values follow the standard conversions from the sRGB color space. 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.
