Crossword Genius

I call for a change of colour (5)

Ross

I believe the answer is:

lilac

'colour' is the definition.
(lilac is a shade of purple)

'i call for a change' is the wordplay.
'for a change' indicates an anagram.
'i'+'call'='icall'
'icall' is an anagram of 'LILAC'.

'of' acts as a link.

(Other definitions for lilac that I've seen before include "Pale purple - flowering tree" , "Plant" , "Pale mauve colour for a flower" , "Fragrant shrub; colour" , "Pinkish purple - shrub" .)

I've seen this clue in the Evening Standard.
