Not seen orange ones before!

For most of the runs of these cleaners they were the same colour
1334/LATE 652 Pink & Rose white, late seniors had same burgandy material bag as 1334. On through to 1346 same colour combinations
Grey, Hop Green/Joquil, smoke pine/swedish green. They diverged after the 1346 came in (although the 1354 & 1354A were the same as Senior, or at least blue) coming together again when the Jade Green 1346 was dropped for the blue version, although they may have been minor differences then - I think the 1346 might have been a darker blue than the 1354. Of course once the ranger series was introduced they diverged completely.
It is just my impression, but I don't think there were that any variations of the Senior in the UK (apart from the Co-op version), certainly not as many as the Junior, and even then the variations tended towards the end or after the 1346 had been dropped from the mainstream line.
