I don't really know how to use the right words to describe what's happening, but I'll do my best. I'm not very knowledgeable about all the specific terminology or anything... 😞
I've used Designer for a year or two now, rarely any problems (and most I have, I can figure out myself) and I've somewhat recently gotten Photo and Publisher.
I'm working on a small charity project and I'm having a LOT of trouble, which hasn't happened before.
The leftmost is the original, still in Photo. The right is the first export. The color became a little more dull. I wasn't sure why, as I haven't really had this issue before, so I switched to designer to try to see if I could export it there. Turns out, that was a HUGE mistake. The colors went pastel, and I can't revert it back to the original without redoing the entire thing.
I usually only do digital art in Designer and I've never had this problem, so I have no clue what went wrong or how to fix it.
I just want the original colors back without having to redo all the masks (I was lazy and didn't separately crop each image...) and I'm now scared this will happen to anything else I use with any of the 3 programs, so I can't open any other files until I get this figured out. I did restart my machine, but it still happened after too. Every time I open the file, or transfer between the programs, it gets worse.
I have the most recent updates for all three, and I'm running OS Catalina 10.15.6, if that makes any difference.
