How we calculate these values

The figures for #355fa3 come from standard color math, shown so you can check them. 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. The Pantone value is the closest reference by perceptual color distance and should be treated as a starting point, not a guaranteed match.
