Frozen Blue 2 is just beautiful to me. In the direct sunlight it's an obvious blue, but in overcast conditions and at night it turns more purple (at least to my eye). I took some photos at varying times and I think a few really show the color transformation even in single photos.
I'm almost done with this car I think, ordered a Vorsteiner diffuser today in 2x2 weave with their 20%/free shipping sale. After that, I think the car is done. The CS cars to me look darned near perfect as is.
