I have had and sold a bunch of both. I have kept one of each for myself, too
. I like them WAY more than I thought I would from looking at the official pics. Once I got them it was amazing how much more 3d the finishes are.
The red is near impossible to take pics of. The main color base I guess would be a very dark almost blood red with a hint of dark gold. It goes from red to gold to brown almost and can even be blackish. It's almost never the same twice.
The blue is just so deep, it's jewel-like. It has less of the color changing than the red but it still shifts quite a bit.
I like the red more I would say because it's a bit more unique.
