Any spirituality based people wanna help with this line?

So here Satan's little friend tells him "it's an amethyst day, you're acting ruby".

But I'm sure this is in some sort of reference. It kinda feels like when people say "OMG Pluto is in Aquarius! So many big things gonna happen!"

But I have no idea what any of it means.

However I'm very fascinated by it at the same time. So if anyone has any insight it's very welcome to this nerd.

Thank you!
