Crossword Genius

Knock or stab (4)

Ross

I believe the answer is:

pink

I believe this is a double definition.

'knock' is the first definition.
('pink' can be a synonym of 'knock')

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

'or' acts as a link.

(Other definitions for pink that I've seen before include "... similar flower - colour" , "Knock (of engine) - garden flower" , "Left-wing" , "Cut wavy edge on, plant" , "somewhat to the left?" .)

I've seen this clue in The Times.
