After defining my colors in the Telerik color theme generator vs wasn't recognizing the emitted code as valid. I had to explore the Intellisense suggestions and try different variations until I arrived at the correct solution:
I'm not sure if this has to do with versioning differences or is a general case. Regardless, I figured I'd let the Telerik team know.
Best,
Nick
