Mixed baby formula.
Dog of a mixed breed.
A mixed wardrobe; a mixed salad.
I have mixed feelings about the new ownership.
People of mixed backgrounds.
Always polite in mixed company; a mixed dormitory.
A mixed doubles match in tennis, a joke unsuitable for mixed company.
Critical response to the movie was mixed; winning the lottery may be a mixed blessing.
I get a very mixed feeling from this puzzling painting.
