Changing color space won't change swatches
BUG NOT IDEA
convert cmyk document to rgb. Swatches won't change. Can change custom but black stays CMYK which is different than RGB 000.
To David Prescott, I've done that but swatches (black) won't change from CMYK. Thanks for trying.
Paying a lot of money per month for stuff that worked before and should still work

File > document setup and at the top of the Document Setup dialogue box change the intent from "print" to "web" an it will convert all colours to RGB, including [Black] :)
