How to connect red black tan and wires to ceiling fan with blue black green and white wires

I do not know what you have coming to the box in the house but I can tell you about the fan wires. White is a common neutral for both fan and light. Black is the hot for the fan while blue is hot for the light. Green is grounding for everything. I wish you box wires were red,black and white which makes more sense to me. Black is/should be the hot. Red could be another hot from a second switch but now I am starting to guess, not a good thing to guess with 120 vac. Test those wires in the box and determine what they are

Black-black
Red-blue
Tan-white

Try that and report back.
