Liberal going inside for papers, bright in colour (6)
I believe the answer is:
florid
'bright in colour' is the definition.
Both the answer and definition are adjectives. Maybe there's an association between them I don't understand?
'liberal going inside for papers' is the wordplay.
'liberal' becomes 'l' (abbreviation).
'going inside' indicates putting letters inside.
'papers' becomes 'id' (identification papers).
'l' inserted into 'for' is 'flor'.
'flor'+'id'='FLORID'
Can you help me to learn more?
(Other definitions for florid that I've seen before include "Elaborately intricate" , "Ruddy, flushed" , "Overly ornate" , "Flushed and flowery" , "With flushed complexion" .)
