Theme4Logic
Free, open-source color themes for Logic Pro.
Theme4Logic gives Logic Pro a new look. Pick one of 13 presets, or tune the key colors yourself, and Logic opens themed: the arrange window, mixer, inspector, editors, transport, and Session Player. Logic itself is never modified on disk or re-signed. Quit and open Logic normally and it's back to stock. It's free, open source, and makes no network calls.
Theme4Logic loads a small theme engine into Logic at launch and swaps colors as they're drawn, so nothing in Logic's app bundle changes. It's safe and fully reversible.
It supports Logic Pro 12.3 and 12.4 from the Mac App Store. On a version it hasn't been checked against, it stays off and Logic opens with its normal colors.
Colors that carry meaning, like record, mute, solo, meters, and your track and region colors, are left alone on purpose. The light theme is still experimental.
