The color I want to change to is not on the color gamut.

[Shahab-Ahmed]

I am trying to change a person's skin tone but the color I want to change it to is not appearing on the color gamut. Is there any way to fix this?

Hi, thank you for your interest.
The color gamut shows only possible color depend on the L channel values as known as grey scale values. For instance, we cannot change white color into black because of this reason.
