Conditional Font Colors

We use a several Excel files to keep track of who has booked retail space with us. We have a main sheet that has every space within every shopping Mall we deal with. We then have different files for each Mall (this is so we can email the file to the shopping mall to show who is booked in each space but they don't see all the other shopping malls details). We have the other files set-up to read information from the main sheet so when we update a cell with the booked companies name it updates a cell on the relevant file.

This part all works fine, but we also change the booked companies colour depending on if they have they have paid, not paid or awaiting invoice. Currently we change this by hand on the main file then on the other files. I am hoping someone maybe able to explain a way of adding to the formula we already use to update the relevant cells automatically to enable the font (or cell if its easier) colour change to be carried across to the other files.
