how-dye-do

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

'who mixed colour to make' is the wordplay.
'mixed' is an anagram indicator.
'colour' becomes 'dye' (dyeing is a kind of colouring).
'to make' becomes 'do' (eg to make or 'do' a meal).
'who' is an anagram of 'how'.
'how'+'dye'+'do'='HOW-D'YE-DO'
