Although the color editions are nice, does each color carry a higher premium is the question? also not sure if it was limited mintage on certain colors as I was not around during that time.
here's the stacks archives:

I love Ravenbits, not sure I'd spend a ton of sats just to get different colors, but definately a fan of them. Didn't find any on ebay sold listings to compare either.
Good luck fishing... might catch something
Interesting that someone would load 12x of them with all the exact same amount

All Ravenbits originally came unloaded if not DIY
For the colors, I would hope that the colors would hold a premium based on their limited mintage
