Hi there cassianno!
Exactly right! I thought that if I just wrote 1,950 icons, people would get confused to find a large number of recolours, so I went with the unique design wording. It's 1,950+ files, but 340+ unique designs that I recolored to get, well, differently colored versions. :)
If you have any questions, don't hesitate to ask away!
... And thanks for telling me about the website bug! :)
