Two missing images in Mini Sphere color picker. (404)

[BobbyBabes]

I just bumped into this repo and was checking it out. I got a 404 on 2 images (see screenshot).
They might just be required for the demo though. Just letting you know.

P.S. After copy+pasting the 2 image URLs from the console to the address bar, I discovered that you have one of the most original and beautiful 404 web pages that I have seen.
