1, How to know the rune's rarity? I know the rune images have different colored frames...but which color means common and which means rare?
2, Marketplace, bought a pack and selected "store", then can't see them? Now I want to open packs, but where're they?

[Diablo™]

yellow = common
red = uncommon
blue = rare
purple = exotic
green = legendary
grey = limited

the pack content can be checked immediatly after the buy, otherwise the pack will be opened and the runes scattered in your collection
