This will be harder to do... There are no accidental grobs attached to note
names grobs, so that approach won't work. 

My next thought is to make a custom engraver, add it to the note names
context, and use it to set the color of accidental note names.  But it seems
that the note names context does not have a key signature property, like a
staff context does. (With a custom note head engraver you can access the key
signature property in the staff context, and use that to identify accidental
notes, but that won't work with note heads context.)  

So I'm not sure how to achieve this...  I'll let you know if I think of
anything.
