Fish I like lacking female’s vividness of colour (10)

I believe the answer is:
brilliancy
'vividness of colour' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'fish i like lacking female's' is the wordplay.
'fish' becomes 'brill' (brill is a kind of fish).
'like' becomes 'fancy' (both can mean to find someone attractive).
'lacking' is a deletion indicator.
'female' becomes 'f' (abbreviation).
'fancy' with 'f' taken away is 'ancy'.
'brill'+'i'+'ancy'='BRILLIANCY'
Can you help me to learn more?
(Another definition for brilliancy that I've seen is " Stroke of genius; superb chess game".)
