idk, I'm afraid "bluey greeny colors" would look too much like a description of the artwork?
there so much material in there tho. "the land at the bottom" (4:50), "flat. no reflection" (4:57)
P.S. about what was suggested before, I think I'm with RFJ on "warm machines" being a bit cliché: in my mind it links to artificial intelligence, and other "machines with humanity in them" themes, which isn't bad per se but feels a bit too generic I guess. Tonal Drift is cool because it can mean so many different things (about the music and the artwork), although to be totally honest, having "tonal" in the title of a record isn't something I would personally like to do. I like the single-word suggestions that were made, like "Ondulation", and "Rarefaction".
