Temperature isnt about colours (5)

I believe the answer is:

tints

'colours' is the definition.
(tint is a kind of colour)

'temperature isnt about' is the wordplay.
'temperature' becomes 't' (abbreviation).
'about' indicates anagramming the letters.
'isnt' anagrammed gives 'ints'.
't'+'ints'='TINTS'

(Another definition for tints that I've seen is " Shades".)

I've seen this clue in The Mirror.
