How do I change color pattern based upon a formula within a cell?

[aemuk]

EXCEL - Can anybody show me the specific keystrokes to direct a cell to be a
certain color pattern based on the following example?

If the entered data in B1 is > data in A1, then make the color pattern in B1
Green
If the entered data in B1 is < data in A1, then make the color pattern in B1
Red
If the entered data in B1 is = data in A1, then make the color pattern in B1
Yellow

Thanks for your help!
