❔ Textmate themes for custom languages?

So it's apparently possible to add support for custom syntax highlighting via textmate grammars according to https://github.com/Microsoft/VSSDK-Extensibility-Samples/tree/master/TextmateGrammar . I can find no other documentation online about doing this with Visual Studio though. I'm just trying to highlight multiple keywords in a different color in my custom language, but I have absolutely no idea if I'm doing this correctly since I'm getting

System.InvalidOperationException: IWpfTextView.TextViewLines is invalid.
   at Microsoft.VisualStudio.Text.Editor.Implementation.WpfTextView.Microsoft.VisualStudio.Text.Editor.IWpfTextView.get_TextViewLines()

System.InvalidOperationException: IWpfTextView.TextViewLines is invalid.
   at Microsoft.VisualStudio.Text.Editor.Implementation.WpfTextView.Microsoft.VisualStudio.Text.Editor.IWpfTextView.get_TextViewLines()

whenever I try to use the tmTheme file and then open the file. If I leave it out, it seems to work and match my two regexes fine. They're just the same color. Is there a way to actually specify the colors?
