One of my best friends made a toolkit available on AOL's HyperCard section called "Color Paint Tools" which let you put color into your stacks (making that hack you mentioned easier). If I remember correctly, HyperCard could show color images via an XCMD but they'd have to be a PICT resource (so it's not a real solution). I think Apple eventually released an update (HyperCard 2.2?) which included an official toolkit for doing this

Apple indeed did - so any stacks uploaded to this archive will likely need to not use the color XCMD.
