Hmmm. I think that, for what I want, (I'm moving a lot of the fiddly bits changes I've made to Transmogrified to a custom theme layer, and then I will play with GLORIOUS COLOR in the user layer), that just setting custom CSS will probably do, but I wasn't sure what would happen when I used it.

Thanks!

ETA: Having thought this through a whee tiny bit further ... I want to be able to call color variables in my CSS, can I do that with either of those functions? The stuff they are printing is escaped...
