This was probably my bad. They were added in r476 (background color) and
r488 (font flags), which are not available as a general download yet
hope ;)). Note that even then, you will need to (temporarily)
remove/rename the configuration/ directory in your Tw config folder as
the files are not updated automatically in order to prevent accidentally
overwriting changes made by the user. Alternatively, you can look at the
current version of the file at

Yeah, its the svg names that are supported, not the whole svg color
definition. However, arbitrary numeric colors can be specified as
#RRGGBB (where RR, GG, BB are two digit hexadecimal values) IIRC. E.g.
#ff0000 for red, #ffffff for white, etc.
