And in the final releases of HyperCard, Apple even bundled a third-party color XCMD in order to pretend that HyperCard supported color. It was really limited though (insert PICT files from disk! change the color of buttons! use the paint tools in color? what are those?)
i think supercard supported color.
Yeah there were a few clones that added color and other features - two are even still around today!
