shocking pink

I'm a little stuck... Click here to teach me more about this clue!

'bold colour' is the definition.
'shocking pink' can be an answer for 'colour' (I have seen 'frightful colour' mean 'shocking pink' so perhaps 'colour' could also mean 'shocking pink'). I'm not sure about the 'bold' bit.

'wine popular doctor chucked into basin' is the wordplay.
'wine' becomes 'hock' (hock is a kind of wine).
'popular' becomes 'in' ('in' can mean trendy).
'doctor' becomes 'GP' (general practitioner).
'chucked into' means one lot of letters goes inside another.
'basin' becomes 'sink' (I've seen this in another clue).
'hock'+'in'+'gp'='hockingp'
'hockingp' going inside 'sink' is 'SHOCKING PINK'.

'shows' is the link.

Can you help me to learn more?
