[Working with no embedded profiles]

All right, thank you all for your time/answers! The conclusion is to use sRGB (as an embedded profile in the source file, or proof to it) and dont save it to the output file. Software (browsers as well) that supports color profiles will assume that images without an embedded profile are in the sRGB profile. Software that doesn't support color profiles will use monitor's profile, which is most likely to be sRGB as well, and stripping color metadata from PNG and JPEG files makes their colors consistent with GIF as well as with colors in CSS/HTML.

Thanks for your reply Neil! I know the benefit of color profiles, and I use them when I work for print. I use them in my RGB source files as well, but when the output will be used online, In my experience, it's still better to use output-images without embedded color profiles, as still not all browsers supports them. In websites there are other elements with colors (html, css), not just images, and  if you pair them with images with embedded ICC profiles (even if you use sRGB) they often mismatch.

That being said, I'm still looking for a solution for proofing my source files, to match the output files without icc profiles.
Is there a way to proof colors in Infinity Designer for 'no embedded profile'?

Thanks for the quick reply! I've found that option, and I know the way to export an image without ICC embedded. My problem is that the exported image differs in color, and I would like see the end result (color-vise) during editing. As I wrote I'd like to proof colors, so I can see what the end result will look like.

I've uploaded a screenshot. From left to right: Affinity Designer, Preview, Safari. Notice the difference in the skin color. I'd like to find a way to see the same colors that will appear on the exported jpg (with no embedded color profile) _during editng_ the file in Affinity Designer. In PS the way to achieve this, is to proof for your own screen. Is there any way to achieve this in AD? To have color consistency during the worklow, if I know, that the output will not have an embedded ICC?

In Photoshop, if I turn on 'Proof Colors', and in the 'Proof Setup' I choose my own monitor's profile (PS calls it 'Monitor RGB') I get to see the same colors during editing (in PS), exporting (save for web) and in Finder (in Quick Look, or in Preview), and even in all the browsers (Safari Chrome). As not all software can use ICC profile, I find this the best way, to ensure, that the image will look exactly the same everywhere.

I'd like to do the same in Affinity Designer: I'd like to export an image with no embeddded color profile, but after export, the colors are slightly different. What I'm looking for, is a solution for seeing the end result before exporting. So basicly I'd l'd like to proof for 'no profile', or for the monitor I'm using. I'm familiar with the soft proofing method in AD (with a Soft Proofing adjustment layer) but I dont find 'no profile' option in the 'soft-proof' dialog. I found a profile named 'Display', and I thought this is how AD refers to the monitor's own profile, but It looks like this is not what I was looking for, as it doesn't change the colors at all.

Is there a way to proof for no profile? Or a way to install a custom profile (my monitor's)
Please advise! Thanks in advance.
