How we calculate these values

The figures for #255151 come from standard color math, shown so you can check them. 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. The Pantone figure is the nearest match in our reference set by perceptual distance and it is an approximation, not an exact spot color.
