Summary: No matter what settings you change, “Operators” in IronRuby are  
always green (hex 008080).

I put a few hours into investigating this (  
[http://ironruby.codeplex.com/workitem/6117](http://ironruby.codeplex.com/workitem/6117) ) and as far as I can tell,  
it’s a bug in visual studio.

The language classifier used by IronRuby (DlrClassifier) is classifying  
operators using PredefinedClassificationTypeNames.Operator - this is  
apparently the correct thing to do, but when you do this, the text  
always  
comes out green and completely ignores the IDE fonts and colors  
settings.

Tweaking the classifier to use anything other than  
PredefinedClassificationTypeNames.Operator works, and allows you to  
change  
the color in the IDE settings, but for some reason that I cannot figure  
out, using Operator always produces the same green.

Commenting out all logic other than the core classification logic (brace  
matcher, etc) doesn’t affect this, and it is also reproducible using the  
microsoft Ook language sample from here:

> **[Browse code samples](https://learn.microsoft.com/en-us/samples/browse/?redirectedfrom=MSDN-samples)**
>
> Get started with Microsoft developer tools and technologies. Explore our samples and discover the things you can build.

Given that I can’t seem to affect it, and it is reproducible in the ook  
integration, this leads me to believe that it’s visual studio itself? I  
tried to figure out what the C# language does (as you can change  
“operator” colors in C#), but I couldn’t find any classification stuff  
when running reflector over any of the standard visual studio libraries,  
so I can’t figure out what it’s doing differently to make “operator”  
work.

At any rate, I have a small patch which switches the classifier from  
using  
“operator” to “script operator”. With this patch you can change the  
colors  
for “script operator” in the IDE and have them affect operators in  
IronRuby code

If anyone has more knowledge about VS integration and may be able to  
help  
with why the standard “operator” coloring is not working, I’d really  
appreciate it.  
If this is a bug in VS, do I need to file something somewhere? I’m not  
sure where to go with it.

Thanks, Orion
