ORION-70 Projection Console — Amber Console

Gas emitting directly. No phosphor in the stack. A beam on a phosphor, which emits and then persists. General purpose · built to be read Specialized · built for an instrument Simulation · never a color Style & engine · never the hardware The retrace band is part of the CRT simulation, and there is no sweep across a plasma panel to switch off. JS Effects need the CRT simulation and a phosphor that holds long enough to see. JS Effects off: no ghosting, smear or framebuffer decay. Everything else here is CSS. Ghosting — rewritten text leaves its old value to decay Scroll smear — the image trails while the page moves Framebuffer decay — the old screen drains behind the new A gas in a sealed gap, struck by a sustain pulse. It emits directly — no phosphor in the stack — so the panel lights one hue and varies only how hard it is driven. Argon puts most of its output past 700nm, where the eye scores under 0.01 — so the 696.5nm peak above is the strongest line, not the color. What you see is the faint 415–475nm group, a hundred times weaker and a hundred times better placed. It is also why argon is a dim GAS — though not a dim palette: every stop here is solved to the same contrast ratio as every other, so what changes between displays is the hue, never the brightness. Krypton spreads its visible output across a blue-violet cluster at 427–450nm, a green line at 557.0nm and a yellow one at 587.1nm. Spread that wide integrates close to white, which is why the panel reads violet rather than any one of those colors. A beam sweeps a phosphor coating, which emits while struck and then persists. The color belongs to the phosphor, not the beam; the P-number names the compound. The gas the plasma panel was actually built on, and what this framework opens to. In a low-pressure glow the 2p→1s array dominates — the lowest excited states that radiate visibly, populated far more heavily than anything above them — so the discharge is one narrow orange-red rather than a mixture. Nixie tubes and the first flat panels ran on it. The palest gas here, and structurally so: helium has no low-lying manifold to dominate the way the heavier gases do. Its visible lines all fall from n=3 and n=4 at comparable energies, so none outranks the rest and every one contributes. That integrates to near-white with a pink cast — 587.6nm carries the luminance while 447.1nm and 667.8nm pull it off the…
