Thank you all so much. Just removing " solved case and when testing on series of images it confirmed my impression. Getting info from histogram gives better results (for me) than use of simple color reduction.

If you want to keep quality to 100 option `-sampling-factor 1x1` doesn't matter much but is always good thing to include it when dealing with JPGs. Simple `-unsharp` will do miracles when downsizing. Parameters you have to choose according to your taste. For me `1x1` is good enough although some may ...

I've found alternative:
But I'd like to solve original problem - going through histogram gives some more options for color choosing.

TIA

I've found your scripts but instead study them dismissed them because they didn't have auto option

First of all - thank you very much, mask is working. Second - sorry i was copying links to images and mislabeled one of them. Third - these are not my photos, just among first examples when you put 'bad white balance' in Google Images Fourth - 'my' method is variation on use of Photo filter ...

Here is another example, this time with cold image. Original: http://www.witkacy.hg.pl/badwb/cold.jpg Your method: http://www.witkacy.hg.pl/badwb/c1.png Your method: http://www.witkacy.hg.pl/badwb/cold_corr.png As you see your method with Blend compositing overshoots. In case of warm images it makes ...

Ups sorry. Between 5 and 6 - use PS Color layer blending mode Color (in IM jargon: compositing mode - Colorize) to blend two layers. In this particular case complete invert/negate is almost undistinguishable from invert of just Hue channel so posted only one example. But difference is there and in ...

Thank you for your help but blend mode doesn't cut it (already tried). In this case it is working because example is in so bad state that any correction is improvement. But look here: Original image: http://www.witkacy.hg.pl/badwb/warm.jpg Your method: http://www.witkacy.hg.pl/badwb/w1.png My method ...

I cannot create in IM multi-layer TIFF files which would be readable by PS. Found post on forum by one of IM developers that they don't plan to introduce this feature (note that this post was few years old). Cannot find on the web exact copy of this but here is slightly different version: https ...

Hello, I tried to create auto color correction according to well known PS method: duplicate layer, blur to average, invert H value, set opacity to please, blend in color mode. I hit to obstacles in ImageMagick: 1) best solution would be create automatically two separate layers with appropriate ...

Profile conversion is incomplete without updating of relevant metadata fields. Note: for proper review of problem you may need to download all files into your disk and use program like Windows Photography Viewer (built-in Windows app) which are understanding color management partially. Lets take ...
