Colour export out jpg not match with working file

@Adriana Hwee 326092958fre  Can you show your Edit > Color Settings? It looks like your RGB Color Management Policies are set to Off. As @Abhishek Rao suggested, set your RGB Policies to Preserve Embedded Profiles.

I would also suggest to turn on the warnings for mismatches and missing profiles. They will allow you to make a choice when a mismatch takes place.

Unfortunately PNG files and Illustrator do not go well together.

Opening your screendump causes Illustrator to change the default Document Color Profile from sRGB to your DELL SE2719H monitor profile.

If you would export the file that has the Dell profile as PNG, Illustrator would use that profile, but not embed it during export.

Other applications will look for a profile, cannot find it and use the default, probably sRGB, which would be wrong and cause a color difference.

Hi @Adriana Hwee 326092958fre,

I hope Ton's suggestion helped point you in the right direction. If you’re working with screenshots or images from your monitor, Illustrator might be picking up your monitor's color profile (like DELL SE2719H) instead of the standard working RGB space, which can cause that color mismatch when exporting.

Could you try going to Edit > Color Settings in Illustrator and set RGB color management to 'Preserve Embedded Profiles.' Also, when exporting, make sure "Embed ICC Profile" is checked in the export dialog. This should help keep the colors consistent between your working file and the exported JPG or PNG.

Let us know how it goes or if the issue still persists.

Are you opening screendumps in Illustrator? If so, the Document Color Profile will become the profile of the monitor.
