two colors - need to decide NOW

On thing you might consider if you are going to use the car in the real world.
I have found that I can’t touch up metallic colors like I can “solids”.
Chips look like crap when I try and dab some in them.
And I haven’t been able to “blend” in a big repair.
But metallic is pretty and yellow is a pain in the but to keep clean.
And as long as we are talking practical:
Brown is good because you never have to wash it.
