I'm just looking for a way to do it to every word on the page automatically for several words at a time by clicking a macro shortcut button to save time.

The criteria is that the first 2 letters of the selected word are in one specified colour and the rest of the letters are to remain in black. Also the font needs to be increased by two points and I'm not sure how to do that, i.e. from 10->12 or 12->14. Because the particular font is a bit smaller than normal typefaces.
