The Rainbow label was active for most of the 1980s.
The label had two distinct designs.
The first label has an MCA-like multicolour rainbow logo on the label.
The second label has a less slick black/white/red label.
Other, simpler variants exist: a red/white design label, a red/white text only label and a black/white text only label.
These label variations do not seem to follow a simple chronological order.
The logic behind the numbering system and the variation in prefix are things I've yet to decode.
