Here's the template file with the correct colors in EPS format, I have no idea how it'll come out but it's the best I can do. I guess I could try .PDF but that might not preserve the colors very well.

One of these colors should come pretty close to the Porsche display when printer on your printer and combined with the amber screen.

I'll try moving the grounds tonight and a few other experiments I have planned, and see if that makes a difference. I'll let you know what I find.
