What rerolls gold chests?

[Urqui]

Do pinks reroll into gold chests? Because silver is a green or rare & copper is white or uncommon..
Or does chest color not matter & silver reroll into gold chests?

You had a nice start. Silvers are rares, but based on the dark blue coloring I'm going to assume golden is epic. Thus a silver would re-roll to a golden. Maybe.

Common elite rerolls into silver (rare) and silver rerolls into golden (epic).

I didn't think luck affected chest drops.
