Using the top bar, move the centre arrow to suit your taste. You may have to do it for each color and you may have to do it differently for each photo so I cannot give you input/output as each photo may be different.

Hi sallyanne,

Thanks for your advice.

After testing for several days I think the best approach to restore faded photos tinted with yellowish color is;

Colors -> Colors Balance
pls refer to screenshot upload

It is time consuming not only with 2/3 clicks.

But I still can't understand their features:_
Shadows/Midtones/Highlights

Preserve luminsity/Blending Options

Mode/Opacity

Can you help?

Can any folk on the forum shed me some light?  Thanks

Regards
