Yes, colorize, most likely. I haven’t tried it, but it looks just right.
2 Soupy, kofa
Thank you for your help.
colorize won’t allow you to match the colours in an automated way.
The modern, and recommended way for colour grading is color balance rgb (already available in 3.8).
https://docs.darktable.org/usermanual/3.8/en/module-reference/processing-modules/color-balance-rgb/
Aurélien, its author, has just published a new video on colour grading:
I think you’ll also find this channel useful:
There’s a spot module there, too. It is necessary to recompile src.
The rest of the tools rely on channel histograms, and you just need to fill in certain selected areas.
I’d rather wait. Racing betas, no way.
Several of us here have been using the dev builds for years. Of course, there can be issues, but they are fixed quickly, and using those dev builds helps deliver tested software. You get new features more quickly, you pay with a bit of extra risk. To each his own.

Hmm. yeah?
I’ll try to build a program from source. It makes no sense to build it from the ports that are available for macos.
If only to install darktable-devel from ports, so that then to compile that one from the sources, not from the ports to build the program, but from from the off-site.
Yes. When I have time, I’ll try it. Thank you again.
@wpferguson Bill posts a new build every Sunday if you are on Windows…just search the forum or scroll back for Windows insider.
You can run this parallel to any version you currently use quite easily using command line switches… I can elaborate if any of that sound useful
mac OS
Right I am an idiot I forgot…should have recalled. I recall some osx builds put up too by @MStraeten I think …I will have to go searching…
EDIT
Here 2 days ago
That’s it 
I see that here I will not be left alone with the problems, even if I want to ))))

From the bottom of my heart, thank you
Your welcome…I build Windows every few days and touch wood they can have some minor issues but overall nothing insurmountable or generally corrected quickly…I am just a hobbyist and so I don’t rely on DT for an income so maybe others have a much more cautious approach…I find it really helps to learn to follow and participate in trying the new feautures…
I hope you enjoy your ongoing journey with DT…
Do you know if you can switch from the lightness, hue, and saturation sliders to color circles in the color balance tool, where the 4 ways are, or are there only sliders?
No, as long as the program is stable. One minus - it slows down when you move the different sliders in the tools. There is no opencl support for this program on mac OS.
But I also have an old computer. i7 processor, but ivy bridge times. with an amd hd7970 video card. This is still a computer from the days when memory was ddr3.
The davinci resolve of course flies and I don’t notice any problems at all, but that proprietary software, which is probably loaded with a lot of resources.
But maybe you can somehow enable opencl support in this program that would not slow down the program?
This is the fault of macOS, not darktable. Apple dropped openCL in favor of their proprietary Metal API. So not a whole lot we can do. Also there are only a few Mac devs on the dt team.
Indeed. now switched to opencl in resolve - a complete hangup) back to metal.
Well, no, so no. No big deal.
They are sliders, their UI is not configurable.
Well, no, so no. No big deal
No, seriously. At one time I was even looking for sliders. The ability to search for color at a specific radius.
Without control panels (balls) it can be difficult to use the rings. And control panels cost a lot of money.
I think that is a MacOS thing…no support or poorer for OPENCL…The DT pipeline is also a beast as the dev’s will admit and efficiencies there maybe in the future will help tremendously.
There is a program variant in the works…very early days using vulkan that I gather is very very fast but still evolving…you can google or search the forum for vkdt to learn more about that……
I just recently updated my hardware as it was sorely needed but things like the diffuse module which produce great results are a beast on older hardward…so I now have a 30 series Nvidia card , 12thgen intel, and 64gb DDR5 with nvme drives and it helps a lot……
For the sake of interest, I installed windows. Under windows the program began to crash often. version 3.8.1 from the off-site.
I sent a bug report, but I think it’s a problem with my video card and opencl (windows). Davinci resolve is also screaming about gpu chip errors (windows). I have been using different drivers for my video card. the result is 0. I have raised this topic on this forum, but no one is aware of the problem Drivers for AMD/ati graphics cards . And on the profile forums classic genre - update drivers, buy another video card, reinstall windows.
But the program even with opencl (windows) support does not work fast. If we add the moment of program crashes then I think I’d prefer mac os without opencl))
It is better under mac os. Davinci resolve works reactively and without crashes. It has only crashed 5 times in 8 years.
And let darktable work without opencl, but at least it won’t crash. It does not crash there, unlike the windows version.
On another forum recently a user was experiencing at ton of issues crashes, kept reinstalling and trying a different OS…in the end they had bad memory stick…It might pay to run a comprehensive hardware diagnostic if you are having lots of crashes just to rule out something like this happening to you…I run DT on WIndows and generally don’t have too many issues even as I am building it and staying current every few days…that much crashing must be a sign of something…hopefully you can track it down…

If you change the video card to nvidia, there is no problem.
More accurately, if you move the video card to another computer, the problem will happen again.
I service about 40 machines in three small offices. It is possible to combine the hardware temporarily.
Putting a more powerful power supply makes no difference.
AMD hardware is not good friends in pc. They have good hardware, but the software for windows is not always smooth.
On mac os it works. And with opencl (before) and metal (now).
windows = nvidia
mac os = amd ati ))
But that’s a luxury, that would only keep windows, change the video card forever.
