Any app that has RGB Levels can do that for you, although RGB Curves would give you greater flexibility. Alternatively, some apps have linear color mixers, mine has a three-channel RGB mixer - 9 sliders ... very flexible!

I think you should look for an app that saves a side-car file with all your adjustments in it and, more importantly, allows the re-use of that file on other images. Free RawTherapee is one such app.

Photolab2 has the HSL section, but with more colors than RGB, i couldn't get proper results using that, i guess because the bands are too narrow ?

Just about any image editor should let you do that. I edit JPEG images quite frequently and contrary to what you may read it is definitely feasible, you just can't push the image too hard without creating artifacts (primarily banding).

What's wrong with using the Tone Curve in the "Light" panel of PhotoLab? It lets you address the R, G and B channels individually.

Oh i will check for that, not something i normally use, was thinking it should have that but didn't look in the right place i guess ! D'oh !
Just might do the trick, especially if it will do curves, don't need much of a curve the lines are nearly straight on the displaycal graph.

Ok now i feel like an idiot haha !
Yes Photolab2 has the RGB levels in the Tone Curve tab,
and i just tried it, using the numbers from the displaycal profile info even with just straight lines it's almost perfect !
And it does allow more points if needed to tweak it more.
Yeesh the solution was there all along....
Thank you very much for pointing that out Manfred !
