Comparatively drab fawn (7)
I believe the answer is:
flatter

'comparatively drab' is the first definition.
Both the definition and answer are comparative adjectives. Perhaps they are linked in a way I don't understand?
'fawn' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for flatter that I've seen before include "Less uneven; cause (someone) to feel honoured" , "drier" , "Offer insincere compliments, butter up" , "more lifeless" , "flannel" .)
