pigments

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

'a crafty mixture of the black stuff and water for instance' is the definition.
I can't tell whether this defines the answer.

'drunk meg's pint' is the wordplay.
'drunk' indicates anagramming the letters.
'megs'+'pint'='megspint'
'megspint' with letters rearranged gives 'PIGMENTS'.

Can you help me to learn more?

(Other definitions for pigments that I've seen before include "Colouring substances" , "Colours" , "They give colour to oil, water etc." .)

I've seen this clue in the Irish Times and the Irish Times (Crosaire).
