XR749 was silver until circa 1976 - as far as I'm aware "Buzz Lightyear" didn't join the RAF till 1978-79 so he would have been flying said airframe in 1982-83 long after it was painted.
Indeed.
'749 was painted twice in fact, first into green/grey camo in the mid 70's as mentioned and a re-paint into the two-tone air defence grey scheme in 1982.
Here it is at Binbrook on Aug 28th 1982, fresh out of the paint shop.
