Crumpets turned all colours (8)

I believe the answer is:

spectrum

(Other definitions for spectrum that I've seen before include "Band of refracted colours" , "Crumpets (anag)" , "An entire range of related qualities of crumpets" , "Bands of colour in crumpets" , "Full range of colour" .)

I've seen this clue in The Irish Times.
