Let's say I have created a layer on a black-and-white image with a layer mask to colorize some parts (for example skin). I am able to change this with Colorize and change to any color.
But how do I use another image of color of skin (as reference)? Is there a way to select a portion of skin on the color image and apply it to my layer with a mask that I painted so that my masked layer looks just like the skin color of the color image (the reference image)?
I am trying to follow this tutorial, but instead of colorize I want to select a colored image (or portion of colored image) as a color reference. That way it's more realistic.
Or does there exist a GIMP plug-in that will allow me to change dark grey values to take on darker tones of a selected area of colored image and brighter grey values to take on tones brighter tones of a selected area of a colored image?
I wanted to try colorizing a black-and-white photo after seeing this post.
