The 'annotate' also needs to be surrounded by single quotes.

I think 'foreground and background' is better due to the order.

I don't know about the libslang color scheme, but it seems that the
standard color names like 'yellow', 'cyan' and 'gray' are also
available.

Isn't it 'black' and 'lightgray'?

Hmm.. I thought this is for source code displayed with annotate
output, but it's only for jump arrows?  Maybe it's better to rename
this then..  Anyway it's a different problem.

It also works for 'report'.
