Honestly, I just stare at the toaster’s guts and pick whatever color makes it look like a space capsule on a Sunday. If the bread’s browning fast, I go neon orange—makes it look alive. The layout? I line up the keys and LEDs in a “functional art” pattern, but I never actually plan it out on paper. I’ll sketch it on a napkin, start wiring, and then remember I need to check the firmware before the coffee’s gone cold. When it’s clean, it’s because the chaos hides behind a slick matte finish, and if someone’s looking too closely, they’ll see the wire mess I keep out of sight—because that’s where the real optimization happens. So pick a mood, throw some RGB in, and remember to leave a gap for the toaster’s toast‑making heart.
