   > Would you mind reiterating the colors? They differ a lot from the default 
NetBeans style. I think it would be good to have a look at the HTML/JS/CSS 
combination. For that case JS + CSS are highlighted mostly using default colors 
and less extreme where custom definitions are required, the embedding is 
highlighted using a background-color:

   It seems that the embedding coloring is too good for the java code.
   The background color is not kept.
   
   I've tried to use colors used in existing languages.
   With the blue theme, I'm not sure if for the regex expression I should use 
the approach of antlr, to use string color for chars and different color for 
the brackets and operators ?
