Ran, as colors
I believe the answer is:
bled
'ran as colors' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for bled that I've seen before include "Lost blood" , "Seeped (into an adjoining colour)" , "Extracted blood as treatment" , "Showed effects of injury" , "Haemorrhaged" .)
