Is this a puzzle that you’ve actually made, or is it just an idea for now? If the former, I don’t see the point of the “hint” since there’s no actual puzzle to make a hint for (perhaps you should have told us what red[red], yellow[yellow], green[green], and blue[blue] do, and seen if we could figure out the rest). If the latter, where can we try this?
My bad. I wanted people to consider the concept. I thought it would be more obvious than it actually is, so people could theorize on it.
Here's a link although it's not hosted or anything.
