You could use conditional formatting, with a formula comparing values, but
CF won't look at another sheet so you'd need to mirror (through linked
cells) the values from each sheet onto the other 2.

I created 3 spreadsheets with pricing info. I enter prices on a main
spreadsheet and the other two are automattically changed by adding or
subtracting certain amounts from that main sheet. How can I
automatically bold or highlight the cells with changed value? All
three spread sheets need to be bolded when the first spread sheet is
changed. Is this possible?
