These buttons are for the manipulation of colors on your text.
The first button is Text Color . This button only works on text that you select first.
The second button is Background Color . This will only affect the background of selected text (like a highlighter).
Avoid using these buttons unless absolutely necessary. Colors can be tricky. Colors must meet a minimum color contrast level for CSUF accessibility/508 compliance. Here are two resources for you:
The second link will also provide you with the official color codes for our campus blue and orange.
NOTE: Our campus orange CANNOT be used as text color, nor a background color unless the text is black.
