Copper(II) + chromate

[miracle]

hi

i have my chem exam today and there is one question.
Predict the color of copper(II) chormate in aqueous solution.
I know that copper(II) is blue and chromate is yellow ( given in the question)
but what color is that compound? Hope that you can help me with this and if possible, can you explain how you get that answer( i mean how to predict).

thanks a lot
