Yeah... I've never heard VIBGYOR. I did a double-take because this was supposed to be "easy to remember" and that didn't strike me as such, but then I realized it was just ROY-G-BIV backwards. Is this a cultural thing?

EDIT: I find multiple Wikipedia articles[1][2] for Indian organizations/events with the VIBGYOR name, which suggests it's cultural. Some guy's/gal's blog[3] also suggests VIBGYOR is from India.
