Yep. I always thought of the turquoise as 'green' but I think you're definately missing a purple one. I think the registration was GAZ** ? I'm now in search of a photo....... I'm pretty certain it was 'Halcyon nights' and that there may have been only one BAC1-11 500 in that scheme. However, I stand to be corrected on this.
I certainly remember the hosties wearing the 'matching' uniforms. I was once told that the original plan was for the pilots to be issued with the pastel uniforms too!!! If true I bet that went down like a lead balloon! It certainly didn't last into my period at Luton, if in fact it was ever introduced!
