Changing the font colors

1. Select some text and locate the font color icon on the toolbar:

2. In the preceding screenshot, the A icon has a colored line directly below it. This indicates what the last selected font color was. If you select some text and then click on this icon, the selected document text will change to this color. The icon's line color is black by default. To change the color, click on the arrow next to the font color icon. A color palette will appear, where you can select a different color. 

3. Click on the More Colors... option in the font drop-down list. A dialog box will appear, where you can select from a palette of additional colors:

4. By clicking on the Custom option above the color wheel, you are able to select specific tones of color using either the RGB or HSL color models:

5. Once a specific shade of color is selected for a particular purpose, it is always a good idea to jot down the RGB color model numbers. This way, if you want to produce the exact same color again—for example, for some promotional material for a marketing brochure—you can type in the specific RGB colors into the relevant fields to get the same color. This is especially useful when working across multiple Office 2019 applications.
