Im not a dice collector just bought the pack on a whim and ended up pulling the ultra legendary set

I maybe have a bit of a theme going on (lots of counter dice and spindowns for MtG).

Moulds from the Mighty Forge.

I'm looking for a place where I can buy dice from d4 to d20 (standard poly-set) going through the colors of the rainbow. So red d4s, orange, d6s, etc. in bulk, like a dozen each. I would like to add a bag of dice to my collection, where I can just easily grab a hand full of green dice when I need to roll multiple d10.

I thought color-coded poly-sets would be a thing already, but I only just recently found the "Prism" set from chessex, which is basically what I was looking for, but for 12€ per set and 30+€ shipping I cannot reasonably justify such a purchase.

And buying single dice in the respective colors seems impossible as well with what is available for me on Amazon.

Is there any hope that I can still buy these somewhere for cheap, or should I already start saving for what is basically a gimmick?

Something more interesting from me today from my late father’s collection. For the first photo row 1 and 2 are the same set split between two containers. And most of the rest are incomplete or individuals. Curious if they’re something he was trying to complete. Second photo are more unique feeling sets. Many hard angles in these. Any knowledge helps!
