2019 Rainbow
A listing of 13 tokens, curated by :
When I was rescuing MoonCats during 2019, I thought to myself I should make sure I have at least "one of each color" (of the common rainbow 🌈 colors I thought people would recognize; there were no formal color traits defined at this time in the project), and so I rescued several in a row (which also happened to be in sequential rescue order, as there was no other users rescuing at that time) in generally rainbow order, which is this set.
