Aquacolor vs. Supracolor?

[littleexplorer]

Hi! I'm in the market for a super bright, super shiny gold eyeshadow. I saw this makeup tutorial and fell in love. I looked for supracolor though, and I found that it's a lot less easy to get than aquacolor (but still attainable, that's not the issue.) I'm just curious though, what's the difference between supracolor and aquacolor? I feel like I see a lot more people using aquacolor as eyeshadow than supracolor.

I'm sorry if this is a stupid question, I checked the memories and FAQs already so I'm sorry if I missed anything!
