My 1980 Kaypro II computer couldn’t format red diskettes, I don’t know why, but the salesman at the computer store told me I wasn’t the only customer that had had problems with colored disks. At $39.95 for a box of 10, I hated not being able to use them. My next computer (Leading Edge D-XT) handled them fine, though I didn’t need them as much because it had a whopping 30 Mb drive.
Kinda like coloured condoms, not necessary to function but fun none the less.
