Text color decoration in Sharepoint

[Axelcureno]

As a requirement of Merch Cards for running promotions, authors should have the ability to create text in a color that is different from the standard color of a given block. For this example that different color is green.

Is there already something like this applied in Milo? Where an author can set color (or any decoration for that matter) to specific text in Sharepoint?
It would be nice to have a standardized pattern to do things like this to avoid making authors memorize different patterns.
