Get the film ones. Place the lut 3d module above sigmoid (default).
Iāve had themā¦ and waaaay more LUTs 
Iām so stubborn and want to use CC only

Same here 
You will obviously not achieve the same precision with cc. Some suggest having multiple cc or color balance rgb modules. I would need at least 8 and it would be a mess. Auriellen started working on a color equalizer, but Iām not sure if it took off.
Tried Gross Grade?

Sure thing, but these days, I donāt even want to. I try to establish some kind of signature look to my photos - they are not supposed to look exactly like Kodak Portra, Fuji-something etc.
Iād like them not to be perfectly faithful to reality - as many of those analog films didnāt look as if they had Color Checker built-in - but to have some pleasing aesthetic. They cannot look too crazy, though.
My point exactly. I donāt want too many instances, masking, feathering and killing my PC with them.
I see Colour Calibration as extremely suitable solution to my idea - powerful and lightweight.
Plus it will never cause problems with inaccurate masking, as I use it globally.

The biggest problem with the channel mixer is that it is very counter-intuitive.
When comparing your 2 images, the second has less yellow / green. The natural reaction is to remove greenā¦ but no, you have to add green in the blue channel AARGGHH

That means he adds blue where there is green. So basically reduces green without affecting the reds too much.

Yes, I get that, but I find it very unituitive. I have such a rgb diagram open to help my brain get it rightā¦
Thatās actually not wrong. For example, you want to remove the green cast from the womanās face and clothes. Logically, you would like to use the green channel to reduce the green values.
The nice thing about the channel mixer is that you can not only influence the values of the single color channels themselves, but you can also use the different ratios of all three channels to influence the values of the single color channel.
So, in the second step, you then consider which color channel dominates in the face and clothes. This is the red channel.
And precisely because the red channel dominates there, the reduction will also be strongest there if you use for reduction the color ratio of the red channel instead of the color ratio of the green itself:

Hi, thanks =) Iāve watched your very informative video on youtube about the channel mixer.
I think I understand how it works, but when I want to apply it on a photo, my brain seems to melt

Yes I agree. But it is not that easy.
Thatās why my weekend belonged to the channel mixer.
I think I found a way to deal with it.
I recorded my experiences in a report on my website.
A recipe for the channel mixer
Iām sorry, unfortunately only in German. But I think Google Chrome does a good job here, so you can read it in English too.
I hope it helps some others understand the channel mixer better too.

Nice guide I think this will help some users for sureā¦
I also have this little document which is a nice little cheat sheet as wellā¦

I referred to these because you mentioned you were after āa look & feel more or less resembling analogā, but I see what youāre saying. I dontāt see the LUT as a replacement for other color corrections, but rather a way to create a shared boundary for a series of images to contribute to visual consistency.
How do you use it? With the spot color mapping?
Nothing too sophisticated, but gets the job done for me in an elegant way (as I see it )
First instance - for white balancing. But to be honest, most of the time it is set to As shot in camera, and in camera Iāve got white balance fixed to Fine / Daylight.
Second instance as shown in the screenshots below:
channelmixerrgb_Klisza filmowa CC.dtpreset (1.0 KB)
Itās worth noting that this preset is primarily designed to work with base curve at the end of the pipeline, without hue preservation:
basecurve_Moja najlepsza krzywa.dtpreset (1.1 KB)
so these two modules complement each other in colour shifting.

Thanks for describing your process @Leniwiec.
May I ask, @s7habo, if you (or anybody else) can think of a clever way to recreate the functionality of the color look up table module (works in LAB) using the āspot color mappingā or ācalibrate with a color checkerā feature of the color calibration module?
Iād like to map multiple colors to other colors in order to roughly recreate my favorite LUTs without using the LUT 3D module.
This is something very technical and I am the wrong address for it.
For my needs I use multiple instances of the color balance module by masking the corresponding color with hue parametric mask and then shifting the values with hue shift slider.

Thanks for replying. Something tells me all hope is lost. 
Perhaps Iāll create a separate thread for it.
I think for now CLUT might be enough until you have a more elegant solutionā¦ maybe just drag it into display space after filmic or sigmoid and see what you can achieve ??
Thanks. Yeah, thatās what I use now (after sigmoid). Iād be happy not to forever rely on an external cube file to have the file render like it should, though.
