Phosphor amber

Near-black ground with amber phosphor everywhere — one terminal, one century ago.

The CRT amber terminal palette. The ground isn't pure black — pure black on a CRT reads as off, not as dark — but very-dark warm. The amber sits at the brightness of an actual phosphor monitor warming up. A brighter amber is reserved for highlights and active status; a green is kept for one specific UI element (the cursor's friend, the running process).
