This has been asked for a few times over the years but, a) the game has 3 different settings for colour blindness so adding more colours doesn’t help that at all and b) Crate did test having an asterisk by the name, but never implemented it. So yes, there’s a tool you can use called Rainbow Filter to differentiate MIs from other items.
Note however, that whenever Crate update the game the tool will break and you’ll have to wait for it to be updated again for it to work properly.
