Color Mismatch when copy/pasting within Ai
In 27.2, copy/paste, while staying in Ai gives a color profile mismatch warning.
This is weird and should never happen. It also asks to Merge color swatches.
This should happen when profiles mismatch, unless you disable warnings and stop caring about inconsistencies and color conversion that might and will happen. Please check Edit > Color Settings, check options below, and disable those warnings you find useless.
But I’d rather checked the assigned profiles for both files with Edit > Assign Profile, and decided which one you want to use across both.
Please reply back on how it goes for you.
