Based on the observational concept that both the words "better" and "beta" have three letters common between them, I kept the "BET" prefix common. And then placed simply "ter" for "better" part, and finally I used a refractory medium (prism) to represent "A" of "beta". It disperses the white light ray into 7 parts (VIBGYOR).
P.S. - For the critics over here, it's not influenced by Pink Floyd's banner, the idea of prism struck me first! :)
