There are several Keeper NPCs in canon (Leih from the Archer quests comes immediately to mind, she's super fair skinned) that don't have dark black or grey skin tones and instead have a more peach or brown palette swatch.
If you have the option in character creation, it's canon. Most people probably wouldn't heckle you for your skin tone choice, anyway.
