Geiger Counter Green Readout

The Geiger Counter Green Readout is the phosphor-green glow of a radiation survey meter — needle dials and segment digits burning against the black bakelite instrument face and dark CRT glass. It is the canonical P1 green-phosphor color of monochrome computing.

This system distills that Cold-War instrumentation aesthetic: glowing green text and a swinging CPM needle on pure-black ground, scanline texture, phosphor bloom, and monospaced segment numerals — read by light, never on a light surface.

盖革计数器绿色读数，是辐射巡测仪那抹荧光绿的辉光——指针表盘与段码数字在黑色胶木仪表面与暗色 CRT 玻璃上灼灼发光。这正是单色计算时代经典的 P1 绿色荧光体色彩。

本设计系统提炼了这种冷战时期仪器美学：纯黑底色上发光的绿色文字、摆动的 CPM 指针、扫描线纹理、荧光晕染，以及等宽段码数字——一切由光读取，绝不出现在浅色表面之上。
