Hello,

also, what you can do is this. It is not as elegant as solution above, but works for me.

Click on Developer tab and find "Record macro button".
Name it and assign a shortcut to it.
I advise you to use some combination of CTRL + number (start at CTRL + 3, these are not usually taken, test first),
Start recording new macro.
Hit CTRL + D and Font format window will appear.
Pick the color you want and hit enter.
Then stop recording macro.
From now on, whenever you highlight a text and hit your CTRL + Number combination, it will be changed to that certain color.
Repeat the procedure for other colors if you wish.
