How we calculate these values

The figures for #618bb5 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. Two cmyk builds are shown because coated and uncoated papers behave differently, uncoated soaks up ink and needs more of it to hit the same target. The Pantone figure is the nearest match in our reference set by perceptual distance and it is an approximation, not an exact spot color.
