Follow-up Comment #1:

Thanks for your bug report. For the future, bug reports that contain multiple
issues are hard to deal with, it is much better and easier for us if separate
issues are reported individually. I'll do my best to address these.

1. I think this is a known problem, looks exactly like bug #44338. Thanks for
confirming.

2. Your submitted files show that bold works, but your color syntax doesn't
work, that may be a bug.

The following syntax does work


plot (1:10); legend ('\color{red}{\bf a line}');


if that is a viable workaround for you.

3. I don't see any transparency, it looks like a solid legend box to me with
no visible grid lines. Am I reading this wrong or looking at the attached
image wrong?

So I'm retitling this to the single remaining issue, that appears to be a TeX
color syntax that doesn't work.

I'm not TeX expert, so bowing out now, but here are a couple of simple
examples.

This works in Octave


axes ()
axis ([0, 10, 0, 10]);
text (5, 5, '\color{red}{Hello world}');


But the following does not work, using the syntax provided by the OP in this
bug report.


axes ()
axis ([0, 10, 0, 10]);
text (5, 5, '\color{[1 0 0]}{Hello world}');


Is this valid TeX syntax? Is this syntax supported by Octave?
