You can change the color of many things, including text or font, the fill color of a cell or shape, the border of a shape or line, and the background color of a document or slide.
Apply a theme or standard color
After you select the item whose color you want to change and click the related Color button on the toolbar such as Font Color, Text Highlight Color, or Fill Color, you can change to a theme or standard color or create a new custom color.
