Maybe we can just append a "v" check mark for correct syntax and "x" for

"Accessibility means enabling people with disabilities of some kind to
participate in life's activities: in this case, specifically to use your
software. For example:
o Color-blind users may not be able to use your application if you
rely only on color-coding to distinguish different types of
information"
although, in this case, it's not distinguishing different types of
information, it's only providing a hint whose loss probably isn't fatal
- after all, it was arguably not really a hint to people using that
feature before the message to which I'm replying arrived, as I noticed
the background coloring but had no clue what it was telling me.)
Hmmm, after thinking about this, I would tend to the following:
Adding additional widgets for indicating syntax (ok/fail) will reduce
the screen space for *all* users, so this might not be preferable.
As it's really only a hint (maybe a useful one), I think it's ok to do
it the way I implemented it.
It seems to be not quite obivious what the colors are all about, I added
tooltips to explain the behaviour and checked that in.
It might be an idea to only turn the color to red if the syntax is
wrong, and using the default color if syntax is ok.
This might help color blind people as well (at least a bit).
Any comments?
