Nevertheless, I'd like to change the colors in the runtime from all the blues to something more subtle. Is thery any way to do this with environment variables? I didn't find anything in the documentation.

Hi Paul,

all colors/styles of characters in TM are managed via scopes which are assigned by a regexp defined in each bundle's language file like for R in R.tmlanguage:
...
{	name = 'constant.language.r'; match = '\b(T|F|TRUE|FALSE|NULL|NA|Inf|NaN)\b'; }, 
...
which mean assign the scope 'constant.language.r' to everything which is found for the match regexp.

How this scope will be drawn is defined in the color theme (TM Preference > Fonts&Colors).

To change I'd suggest that you duplicate your default theme (press the popup menu in TM Preference > Fonts&Colors > Edit Theme List) and name it e.g. R. Then go to a R doc, place your cursor in front of the character string whose color/style you want to change, and press ⇧^P (Bundle Development > Show Scope). 

E.g. you want to change the color for R constants, place your cursor in front of the string NULL and press ⇧^P, you'll see 'source.r' 'constant.language.r'.

Then go to your (new) theme in the Prefs and add a new style (+ button left from Scope Selector), enter a name, and set Scope Selector to 'constant.language.r'  (without the '), then you can change the color/style and you see your changes immediately in your R doc. 

That's it.

Hopefully it helps,
