Lurid, gaudy (6)
I believe the answer is:
garish
I believe this clue is a double definition.
'lurid' is the first definition.
(I've seen this before)
'gaudy' is the second definition.
(I know that gaudy can be written as garish)
(Other definitions for garish that I've seen before include "Showy, lurid" , "Excessively bright, over-colourful (6)" , "Bright and showy" , "Crudely bright" , "Gaudy, lurid" .)
