Repairing part B&W, part color elevation of heritage furniture

[Alexandre]

Hello !

I am working on a 3D model that i got from 3D scanning a heritage building in my country. Unfortunately, laser was too close to a certain piece of very important furniture and couldn't pick up color on a part of the piece. I've followed tutorials on how to color B&W pictures but so far I've only been able to more or less match the tones using a color fill layer. Is there a solution to get an approximately seamless pigmentation of the black and white part ?

Thanks in advance, pictures attached

Here's how I approached it ..
- selected the area to be retouched and saved that selection to an alpha channel
- placed colour samplers in both the known and unknow areas
- with the feather selection active, via the alpha channel, used selective curves to get closer to the RGB values
- this got the colour match somewhat better but, as the lighting was quite different, used curves adjustments to get a better match in both the lights and darks
- sampling in the known area, painted on a new layer in colour mode
- numerous further curves adjustments, using the masks, to apply selectively, got to this point ...

Thanks a lot ! I'll follow that procedure.

Used the Color Match option in PS Neural Filters and a curves adjustment layer. Close and much faster.
