Change Text Color Of h1 or h2 On Upfront

Hello, I know that the stylesheet would dictate the color of default heading tags. However, with the color changer on the text editor, it would make since to be able to override these predefined settings. Should this work? I can use the color setting on text for some h tags but it seems I cannot do this using the H1 tag specifically. Alternatively, is there an easy way using the upfront editor to change the text size if not using the defualt h tags?
