In a glaringly vivid way (7)
I believe the answer is:
luridly
'in a glaringly vivid way' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for luridly that I've seen before include "Shockingly" , "In a very sensational manner" , "In macabre fashion" , "In melodramatic fashion" .)
