Colour of sky pointer to storm (6,4)

I believe the answer is:

oyster pink

'colour' is the definition.
(oyster pink is a shade of pink)

'sky pointer to storm' is the wordplay.
'to storm' indicates anagramming the letters.
'sky'+'pointer'='skypointer'
'skypointer' with letters rearranged gives 'OYSTER PINK'.

'of' is the link.

I've seen this clue in The Times.
