When exporting a buffer with a black background using Code2HTML it leaves the CSS for variable names as black, making it impossible to see. This has not always been the case, and I am unsure when it changed.

An older output.
After looking at the differences between the html output, the different options within Code2HTML, and date that Code2HTML was last updated I am no longer sure that a change preceded this issue. I am choosing to not close the bug as it would be nice to have it fixed either way.
