finding and replacing all variants of one colour

Virtual external house painters allow you to paint an image from a set of colour swatches. The best ones that I have seen seem to be able to replace the colour while keeping the details and the variations in image colour due to differences of light and shade.

I would like to be able to do something similar in Gimp. Starting from a base colour point, select estimate colour variations based in differences in incident light, and collect select this set of colours. Then replace those colours with a new base colour, applying the same incident light variations to the new colour.

Do you have any suggestions for a basis in existing tools for achieving this?

Yes, that is helpful, thank you Pat. The hint about desaturating is one of those things that are obvious once someone points them out to you.

There's a great site called Encycolorpedia that has the colour values for a wide range of commercial paints. Working from that I can try particular tints.
