Hi Greg,
Can only be done in a macro and very inefficiently, because
it would have to be a volatile macro. If you are willing to do
your own calculate (F9) or trigger a macro when the sheet
is brought up, or you double click from a sheet then you can
use non volatile macros. In other words relying on color
alone is not a good idea and there are many forms of color
blindness.

You can probably get what you want through Conditional
Formatting if you can use a formula to determine what
color you want. Conditional Formatting must not refer to another
sheet, so you might be able to use a helper column.

For the macro solution see

I am adding a background color (Red, Yellow or Green) to a cell to indicate
progress attained. I would like a different cell in a 2nd tab of the
workbook to automatically be updated with the color that was put into the 1st
cell.
