re: Colorize B&W photo of negro and other dark skinned individuals (was: Colour me in)
My fast method here was to select the skintones and put it on a new layer.
A new layer for the dress, the suits, the background wall.
On every layer i used the curves to get the desired colors.
The top layer (burn) is filled with 50%grey, set on linear light for additional modulation of the skintones. Just paint with brown color and a soft brush with opacity 3.
