Sometimes you may want to change how your programs look, for whatever reason. Most people find the colour scheme in Microsoft Office fine, but you may want to change it.
To do so, click on File, and then on Options, which you’ll see down the left-hand side of the screen.
In that pop up box, in the middle of the screen, you’ll see an option to change the colour scheme. You can change it to black, blue, or the default silver.
If you decide you don’t like it, you can always change it back.
