Striking, like Harold's arrow? (3-8)

I believe the answer is:

eye-catching

This clue is a double definition.

'striking' is the first definition.
(both can mean attention-grabbing)

'like harold's arrow?' is the second definition.
(reference to King Harold in the Battle of Hastings)

(Other definitions for eye-catching that I've seen before include "Conspicuous" , "Attractive" , "Standing out" , "Immediately appealing or noticeable" , "Attracting attention" .)

I've seen this clue in The Times.
