See any change of colour (4)
I believe the answer is:
cyan
'colour' is the definition.
(greenish blue colour)
'see any change' is the wordplay.
'see' becomes 'C' (the word for the letter, according to Chambers).
'change' is an anagram indicator.
'any' with letters rearranged gives 'yan'.
'c'+'yan'='CYAN'
'of' is the link.
(Other definitions for cyan that I've seen before include "Bluish-green" , "Greeny blue" , "Primary blue colour in printing" , "Blue hue" , "Printer's blue" .)
