Does the following sentence make sense?

I took a survey on how many cars of which color were sold last month.

For example, this survey says that five red cars were sold, three black cars were sold, ....

I am not sure whether the "of which color" is correct.

Could you please explain why this expression may be wrong?

Neither "which color" nor "what color" sound right to me. How about:

I took a survey on how many cars of each colour were sold last month.
