Hi @nancytreads_xpo,

Currently, headers have a default color across the site. If you are looking to make all headers across the whole site a different color custom CSS could be developed and applied to modify the text color of a header class, but there is not currently an option to select a different color for a single header on Wiki pages. You can learn more about how to Customize and apply Custom CSS as well as see many frequently applied sets of code already developed for you to use.

Alternatively, we do support using hex color codes to color characters and cells within tables. You can learn more about formatting the color in the Formatting Colors Section of the Tables Help page.
