Could not find an existing thread on this, but I've seen anodized aluminum trim rings in red and blue that fit the speedo, tach, and two center round A/C vents (can't remember if it was in the Moss or Mini Mania catalog). Does anyone have these? If so, do you have any pics?

 

MiniMania sells the trim rings you're looking for. They are the only ones selling them I believe.
I opted not to fit them because they only offer the four trim rings you mentioned. I decided on the chrome trim because I wanted additional trim pieces I could add as my funds allowed!

 

I actually placed an order for those rings from Mini Mania back on the 5th of this month... and haven't heard anything since the original order confirmation. No email, no credit card charge, nada.

So I would love to describe them for you, but no can do so far.
