How do I populate a cell using another worksheet as a reference?

For example, if Sheet1 looks like this:

    A    B    C
1     Part    Color    Price
2    Desk    Black    200.00
3    Chair    Black    100.00
4    Lamp    Gold    50.00

Sheet2 looks like this:

    A    B    C
1        Black    Gold
2    Chair    100.00    150.00
3    Lamp    35.00    50.00
4    Desk    200.00    300.00

I want column C in Sheet1 to pull the price depending on the two crietria.

Any ideas?

Thanks.
