inline error message colors...

In NetBeans 4.1, inline error messages were a light blue ([89, 79, 191] 
from http://ui.netbeans.org/docs/inline_errors/index.html, about half 
way down).  But this document is old (Sept. 2003)

In 5.0 - 5.5, it seems the color for these has changed to some shade of 
red (it's still inconsistent in a few places though - yes, I have filed 
bugs, though I think there is one more place still mixed up).

So my question is for HIE, where can I find documentation on what the 
current inline error color is supposed to be and where in the source 
code (or at least in what module) is it defined?  We already have our 
own private copy (of the old blue color) , but if there is a shared 
version, I'd be happy to use that one.
