I have several sets of dice, but I'm looking for color specific sets. I want to have about five full sets of dice where each complete set is 7 different colors so that I have 7 blue d20, 7 red d12, 7 black d10, 7 green d6 and so on. That way when I need to roll 4d10 I know to grab the black ones. The actual color assigned to whatever dice doesn't matter as long as each has its own. It's not really a problem when looking for 4d4 among 3d20s but searching for 3d12s among 4d10s, 5d8s and 3d20 can put a lull in the excitement when smiting the wicked. I've searched all over Amazon and Google and I can't find anything that's not too expensive. Any ideas?

There are lots of shops that sell individual dice online, such as https://www.thediceshoponline.com/. You can pick a colour and order however many d20s, d12s or whatever you want

Great, that is exactly the kind of site I'm looking for. Unfortunately I am in Texas and the over seas shipping came out to 3 times the price of the dice lol. I must continue my quest.

There are dice shops everywhere. What about https://www.dicegamedepot.com/
