Which of these sentences is grammatically correct?
What two colours is this jacket?
What two colours are this jacket?
Thanks in advance.
We usually just say 'What colour is this jacket?', even if it's multicoloured. In your sentence I would also use "is". (the emphasis is on 'jacket')
'What (two) colours are on your (jacket)(flag)?' is correct. (the emphasis is on 'colours')
