You'll need to use ActiveX. How familiar are you with ActiveX? You can record a macro to do the same thing in Excel then look at the VBA code in Excel and try to copy it over to your MATLAB code. See my ActiveX demo, attached.

No. MATLAB has no way to directly change the color of cells in Excel other than ActiveX, none that are practical or easier anyway. Perhaps you want to make an Excel macro that your user can run to colorize the cells that need coloring.
