Very nice. On different coloured fire trucks Coventry in England has yellow ones I believe.
I believe that Coventry only had yellow fire engines briefly in the early 1970s. Diane and I were married in 1972 just before Christmas and went into Coventry and saw one in the city centre as the centre piece for a collection for the Fire Services Benevolent Fund. This was about the time the new colour had been introduced. Earlier on, West Sussex had some bright yellow fire engines, and later on Somerset had a yellow RTA unit based on a Mercedes van.
The Isle of Wight was the last brigade in England and Wales not to have red fire engines. Until the early 1990s they, rather appropriately, had white as the main colour with a red stripe round the waist, and very good it looked to.
In the 1970s, the Home Office ruled that fire engines had to be red in England and Wales, though no specific red - there is no official colour called fire engine red. This regulation doesn't apply to Scotland, however, where Grampian Fire Brigade have white fire engines. In England and Wales, support units such as control and command units don't have to be red, however, and are often white.
Anyway, I've rambled on a lot here and so I'd better stop and take my anorak off!
