Normal colours (8)

I believe the answer is:

standard

I believe this clue is a double definition.

'normal' is the first definition.
(associated in meaning)

'colours?' is the second definition.
(I've seen this before)

(Other definitions for standard that I've seen before include "Basic criterion" , "'Reference point, touchstone (8)'" , "Normal; flag" , "possibly rose" , "Typical, normal" .)

I've seen this clue in The Globe and Mail.
