Simply loved fuss and colour (6)
I believe the answer is:
adored
'simply loved' is the definition.
'adored' can be an answer for 'loved' (similar in meaning). I am not sure about the 'simply' bit.
'fuss and colour' is the wordplay.
'fuss' becomes 'ado' (synonyms).
'and' is a charade indicator (letters next to each other).
'colour' becomes 'red' (red is a kind of colour).
'ado'+'red'='ADORED'
Can you help me to learn more?
(Other definitions for adored that I've seen before include "Worshipped, loved" , "Worshipped and revered" , "Cherished" , "enjoyed very much" , "Idolised" .)
