Alternative sentences are:
" Run Off You Girls - Boys In View! "
" Roll Out Your Guinness, Boys, In Vats "
Some may find it easier to remember the spectrum in reverse-order as a single word:
" V i b g y o r! "
From "Moleshouse" (4/01) comes another way to recall the spectrum:
Remember it as a person's name: "Roy G. Biv"
First name = Roy - red, orange, yellow
