Interior toggleable red/white dome LEDs

Hey all,

In my quest to make the coolest (or at least top 5...) Prius v's on the east coast, I'm looking into improving the interior lighting.

Originally I just replaced lights with LEDs and added panels with adapters to the festoons. But it's all white.

I'd like to keep the white as an option, but I'd also like to 1--add another trunk light wired to only come on with the existing one, and 2--make some kind of setup (so long as it looks reasonably clean) where I can toggle the front dome lights (two in front and the one in the middle) to red, ideally with one switch, to hopefully preserve night vision most of the time.

Anyone ever set up such a thing? Or have videos/guides you'd recommend?

Chaining power for LED dome lights is easy. But I also wouldn't know how to go about carefully making cuts in the headliner, or what would look smoothest. I'd be happy to (for example) mount an identical panel to the one in the middle directly behind it, just with a red LED panel instead--but I'm stumped on the front or how to be able to tell it "white" or "red" with a flick.
