Oops. Crap. I again confused the livetable with something else.
Sorry for the noise.

 LiveValidation used to turn the borders red on the bad fields using CSS but
 I removed it
 because it was unfriendly with the Toucan skin.

 I am not sure I get your point. This is not only a stylesheet change, since
 I need the field to be styled by the livetable JS code. This is more a
 matter of, do you agree that it is useful to highlight applied filters in
 livetable ? what do you think of the implementation ? and what do you think
 of adding a new color in the color theme for highlighting since using the
 standard one is not the best option IMO ?
