With all the explanations, me, myself I would have tried, at least, blindly the step by step EVEN if I see nothing happening, up to the very end to see if the method is working or to validate it, and NOT STOPPING at the first step because I don't understand the tool yet... (although I thought I gave you some explanations in the "step by step" on my previous post, but anyway and in case of... ➤ more about the color picker ➤ https://docs.gimp.org/2.10/en/gimp-tool-...icker.html )

Clicking the wall with Color Picker tool is without response.

Pls refer to images upload

You did got a response ➤ Color Picker did change the FG on your GIMP see the screenshot of your screenshot. But you did not pay attention...

➤ now use this color to fill the new layer

"Set foreground color" already selected.

Clinking the "Color Picker" starts "Change Foreground Color" screen.  Pls refer to screenshot

Sorry, I couldn't find here
Colors -> Auto Balance

To restore faded photo I always try;

Colors -> Auto -> White Balance

OR

Colors -> Levels -> Auto Input Levels

I have tried "Auto Input Levels" before starting this thread.  Pls refers to image upload.

The white wall becomes a red wall.

Those solutions are NOT ALWAYS working
