The approximate hue of human skin is roughly 22 degrees in AdobeRGB. As it is a real world color, the hue varies with the soft proof color profile. In ProPhoto, for example, the hue is roughly 31 degrees, in sRGB it is 20. High saturation and brightness can distort the appearance of skin tones particularly at Lab* lightness above 70% for saturations above 50%. A useful feature would be a skintone line on a tool such as the skin tone version of color tool that adapts to display the correct hue for the chosen soft proofing color space, and shows both the Lab lightness and saturation all in one place, to allow for a simple adjustment to bring skin tones closer to the real world skin tone colors. It would provide a convenient reference especially when working with subjects of varying ethnicities. If you combined something like a simplification of a video vectorscope with the touch up tool that already selects the skin of the subject, and included a slider that allowed the user to shift the hue, saturation and lightness of the facial, neck and body skin to align with the skin tone line that would be extremely powerful.

Current workaround
Most of the information to measure skin tone is already can be found in Capture One. But, you have to know the correct hue to use as a target. The Lab lightness can be displayed, and the hue of the selected point is indicated in a small box in the skin tone color tool. So, skin tone can be checked but it is awkward and one has to select multiple points to check and adjust it. |
The addition of HSL color readout, currently in beta, will make checking skin tone much easier. Setting uniformity of the hue to 100% (or thereabouts) in the skin tone tab of the Color Editor already drives the covered hues towards the target very nicely. So, a simple way to implement this suggestion is to also add a pre-defined target to the skin tone tab of the Color Editor that remains consistent with changes to the proof color space, as do the other HSL numbers in Capture One.
