I opened the loot boxes that i get by voting,so far not even a single red 
If anyone wants to give,trade and take any colour from my inventory if you want
your best bet is using .75 credits to gamble a random item(the option will show up under “craft” once you have 1 credit or more)
lootboxes basically never give r10’s, and even less so red colors
plus red’s are sold for stupid amounts of dp like 50,000dp a few years back
and i doubt anyone wants to trade unless its a unique vanity set or something of similar rarity
