You can choose pick of following colores:
To get a colored text first write down the text you want to be colored. Then mark the text passage/ word.
After marking it open the "Text Style" drop down menu in the red box at the left. And choose your color.
Your text/ word appears in the color you chose.
The only thing you need to mind is the order you format your text.
It's not working if you first choose a bold text and a heading and after that a color.
First choose your color and then further format your text.
