Chromatic Orrery lets you pay for colorless costs using colored mana

[[Chromatic Orrery]] says

You may spend mana as though it were mana of any color.

But colorless isn't a color, so you shouldn't be able to spend mana as though it were colorless.

Potentially related to #10565 as well. @Susucre is this something you were looking into?

I'll try to look into it. Hopefully this can be done without a big engine change. Those continuous effect affecting payment are weird (and lack clean UI to be used, see Jegantha issues.)
