I completed the challenge, but it won't go to the next one

Is there an issue with the Use RGB to Mix Colors challenge, or is there something going on with the site today? It has been stuck on that screen for a good while, and refreshing and clicking submit again does not help at all.

Thanks for any and all answers,
