Fauvist bringing a bright colour back, following fashion (6)

'fashion' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'fauvist bringing a bright colour back' is the wordplay.
'fauvist' becomes 'nia' (I can't justify this - if you can you should give a lot more credence to this answer).
'bringing' means one lot of letters go next to another.
'a bright colour' becomes 'red' (red can be a bright colour).
'back' shows that the letters should be reversed in order.
'nia'+'red'='niared'
'niared' in reverse letter order is 'DERAIN'.

'following' is the link.
