There are some stories where the title calls out for there be a way to put color in at least parts of the title. For example, Greenies should have the letters "e" be in green. Stories about Brownies should have the "e" in brown. It isn't a problem with Blackeyes, since the letters are already black. And there isn't an "I" in the title.
The story and chapter titles on a story is preset as red by the SoL stylesheet but colour can be included in the story text, I do it on a regular basis with the relevant stylesheet commands. SoL accepts only red, green, and blue with black as the default.

Used to be. Not anymore. I removed the colours from headers when I introduced the style switcher. It's also why I changed the style for the blockquote from blue.
