more colors
Currently dot.cc
has an hardcoded list of 9 colors that are used to colors acceptance sets, and highlighted states and transitions.
With the new highlight-languages
code of @aga, each state should be given a color that uniquely represents a language, but the current code in dot.cc
will be cycling over the 9 colors, possibly confusing the viewer.
We should probably add more colors to this list. (Maybe we want to support some user-supplied palettes in the future, but I'd like to avoid this complexity until it is really necessary.) Maybe extending this to 32 colors (one for each supported acceptance set) should be enough.
I think the 9 original colors come from http://www.mulinblog.com/a-color-palette-optimized-for-data-visualization/
ColorBrewer has some palette for up to 12 classes http://colorbrewer2.org/#type=qualitative&scheme=Paired&n=12
