Colour of the mouth reflecting bite in odd cake (5,4)

'colour' is the definition.
I know nothing about this answer so I can't tell whether this works.

'of the mouth reflecting bite in odd cake' is the wordplay.
'of the mouth' becomes 'oral' (I've seen this before).
'reflecting' says the letters should be written in reverse.
'bite' becomes 'nip' (nip is a kind of bite).
'in' means one lot of letters goes inside another.
'odd' means one should take alternating letters.
The alternate letters of 'cake' are 'ck'.
'nip' in reverse letter order is 'pin'.
'oral'+'pin'='oralpin'
'oralpin' put inside 'ck' is 'CORAL PINK'.

Can you help me to learn more?
