I’d be grateful for comments on any of these problems. Once again, it appears to me that either Darktable is doing something wrong, or I am.

However: what actually happens is that I see many pixels in the image highlighted in cyan.

Now, if I choose “sRGB” as my “softproof profile”, and click on “gamut check”, I shouldn’t see any pixels highlighted, because no pixels should be out of gamut.

If I open an image with an sRGB colour profile assigned to it, Darktable should show me an image that contains no pixels outside of the sRGB colour space.

My understanding is that this should highlight (in cyan) all pixels in an image that are not within the gamut of whatever I have selected as “softproof profile” in the right-click menu.

Problem 3: “Gamut Check” produces unexpected results

Or is it the other apps that are doing it wrong? It seems unlikely that they would both agree on a “wrong” result.

Or is it user error - is some other setting that I need to adjust?.

But I don’t think this should be the case.

I also note that if I change between my calibrated profile and the standard “AdobeRGB” one, the “AdobeRGB” one looks more saturated.

It was displaying them with visibly less saturation.

Having worked out how to access my calibrated profile and set it under “display profile”, I noticed that Darktable was not displaying images the same as other applications (eg Affinity Photo and mac Preview).Problem 2: Darktable produces different results using my calibrated display profile, compared to other apps Thanks to some information elsewhere I eventually worked out that by adding my calibrated custom profile to a certain config folder (*see below), I could make it appear as an option in that “display profile” dropdown menu, and I could select it. It’s the profile I have set as the display profile in macos settings, so it’s the profile that Darktable ought to use when I select “system display profile” However I want to try and see things displayed as accurately as possible, and I have a calibrated profile that I made for my monitor using a colorimeter and Displa圜AL software. The image would appear to display correctly if I chose “AdobeRGB (compatible)” instead, which is much as expected, as my monitor’s profile approximately matches the AdobeRGB one. I noticed that the test image would not display correctly in Darktable if I selected my “system display profile” in the menu of options that is accessible by right-clicking on eg. I have confirmed this in other applications using a test image (where a symbol is only visible if the saturated reds are not clipped out). I have a display that should be able to display, near enough, the AdobeRGB gamut. Problem 1: Darktable doesn’t use my “system display profile” for its "display profile"

I’ll try and describe three problems as starters: There are many mentions of problems involving colour profiles on macos but I’m unclear whether these are still ongoing.

I’ve read through quite a few threads in various places, some of which have helped me sort some things out, some of which have ended up getting into technical detail beyond my knowledge. However, I’ve recently got a wide-gamut display which has prompted me to get my head around things a bit more, and I’ve been doing a few experiments in Darktable to this end, but I don’t feel confident that images are being displayed as they should be. I’ve tended just to leave everything as default. I’ve used Darktable for a while, but never really got into any depth on the subject of colour management.
