Watched this YouTube vid last night and remembered you guys discussing Sunset Orange...

This M240i is in Sunset Orange, but you can see they filmed in Canada on a really cloudy day and the car looks more red. In fact, I didn't catch the beginning where it looks more orange, and about halfway through I mentioned to my wife that this red looks really cool, before watching more and realizing it wasn't red. I think in bright sunlight you see the orange come out, but in dimmer light it looks much more red to my eyes. It's a more interesting color than I realized.
