How we calculate these values

Every value on this page for #21243a is computed, not guessed. The rgb, hsl, hsv, cie-lab and xyz values follow the standard conversions from the sRGB color space. 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. The Pantone value is the closest reference by perceptual color distance and should be treated as a starting point, not a guaranteed match.
