Flashy; heroic (4)
I believe the answer is:
bold
This clue is a double definition.
'flashy' is the first definition.
(I've seen this in another clue)
'heroic' is the second definition.
(similar in meaning)
(Other definitions for bold that I've seen before include "Suspended; kept cold" , "Like heavy type" , "Daring, maybe impudent" , "Brave" , "Not timid" .)
