It sounds like several shades of skin tone (8 or so?) were used
in the palette, with remaining colors used for other features.
Then the smooth gradient of skin tones was rendered using error
diffusion from the available palette.

It is usually helpful to use this approach on a photo without large,
gentle gradients, so that "banding" is not too objectionable.
