how to change part of a text into another color

I’d like to change part of my text into another color but can’t find where. I’ve found that I could add another color and apply it but than the whole text changes color.
The webpage I want to change parts in red fonts is http://www.artistsoflearning.com/?page_id=27.
Thanks for your help

I’ve found it, just by toggling in the edit bar…. pff too simple. Item can be closed.
