Allow editing in sRGB colorspace?
My monitor is calibrated using i1display Studio and I'm using the ICC profile it created for my monitor.
Capture One doesn't allow the user to select what color space they want to edit in so I'm assuming that it edits using the loaded monitor profile. When I export to JPG in the sRGB color space, Capture One converts it to sRGB and although it's a very close match, there are very subtle shifts in the hue and contrast. In other words it's not a 1:1 match to what I see in Capture One, although it's close.
Would it be possible to allow the user to edit in the sRGB color space? For instance, DXO and my camera's OEM software allow this. Thus, what I see in those editors matches 1:1 to what I see when I open the resultant (exported to sRGB color space) JPG in every image editor, website, and web browser I throw at it.
It's very reassuring that the output matches 100% to what I see in the editor when I'm editing the image. If, in the output image, there is a subtle shift in hue, color, or contrast it doesn't fully reflect my intention when I edit the image.
Although I can export the image using my monitor's ICC profile, not every image viewer, website, or web browser is color aware. The sRGB color space is universal.

Permanently deleted userYou do not want sRGB as your working colour space - far too limiting - but you can certainly output in sRGB for "universality".
In fact that's really the whole idea...

What you're looking for is (recipe) proofing. In the 'view > proof profile' menu (or add the proof button to your toolbar) you can select which profile you want to preview, a.o. sRGB.

I'm assuming that it edits using the loaded monitor profile
I'm pretty sure that the Capture One editing engine works in LAB, and then the preview and readout values are presented in RGB according the selected profile under the proofing menu (different from recipe proofing). For instance, when my Eizo monitor is set to Adobe RGB, if I select Adobe RGB in Capture One as the proofing profile (View > Proof Profile > RGB > select from list), I get full Adobe RGB colors in the preview, regardless of the selected recipe. If I then select sRGB in the same menu, the deeply saturated colors that were shown under Adobe RGB get clipped in the preview, just as if I had switched my monitor to sRGB emulation mode through Eizo Color Navigator.
You can also preview a particular render recipe by selecting it in the list and then turning on the Recipe Proofing Preview (CTRL+Y by default), regardless of the Proofing Profile that was selected in the previous step.
So yeah, you CAN edit in sRGB, but your image won't really be sRGB until you export it in that color space, only the rendering preview will be.
EDIT:I must add that Capture One does not know what your monitor is calibrated to, it just loads the profile as a transform table to show you accurate colors, provided your profile and monitor are of high quality. It will try to show you the colors of the preview in the selected profile (through RGB Profile proofing or Recipe Proofing), whether your monitor profile (and monitor itself) gamuts allow it.
So basically, the preview profile and your monitor profile are two different things, but the gamut of the two must match closely for the colors you see to be accurate to a given standard (eg sRGB).
If you calibrate your monitor to sRGB specs and get a profile validation review close to 100% (or dE2000 <2), and then select sRGB as a proofing profile in Capture One, you will get accurate sRGB colors in the preview window to base your edits on.

Hey guys, OP here. I have to apologize for taking so long to reply. I just haven't had time to play around with it more.
I also have to apologize to the Capture One folks. The software was doing everything right.
The problem is the DisplayCal software I was using to create and load my profile. That is an example of an over-engineered piece of software if there was one. Unfortunately most monitor calibration tutorials on the internet mention and recommend DisplayCal when, IMO, the software that came with your hardware calibrator would suffice for probably 90% of the people.
The issue I had in my OP with exporting to JPG using my monitor's ICC profile and the color and contrast shifting on the different image viewers I tried or on websites like Flickr was due to to something in the way DisplayCal creates and loads the monitor profile.
I am now using my calibrator's OEM software to create and load the ICC profile and all is well. Everything works as it should. In Capture One when I export to JPG using my monitor's ICC profile and then when I view that image in various image editors and different web browsers, I see a perfect match to what I see in Capture One.
All is well!

That's odd, I always had good results with DisplayCal over the years and across several machines with different monitors, but I guess YMMV. I'm glad you fixed your issue!

Hey OP,
In Capture One when I export to JPG using my monitor's ICC profile...
I really think you should not use your monitor profile in the export recipe when exporting to JPG. This is a wrong usage of hardware profiles. Only you own your sample of your monitor, and images on websites are probably also to be viewed by others, right?
You should always use a standard profile on export (and on softproofing), sRGB for JPGs in your example.

I was about to comment something like that on my last post but I think the OP is using this monitor profile in his exports only a mean to limit the gamut of those files to exactly the gamut of his monitor, and then comparing profile loading matches between different software, but I guess just using a standard profile would achieve the same thing. You are right that a generic, standard profile should be used for files intended to be seen by other people, and on the web, the only standard is plain old sRGB.
