Beige keyboards weren't an aesthetic choice—they were mandated by German workplace safety regs (DIN 66234 & ZH 1/618) that banned pure black/white in office equipment.
The technical reason: extreme contrast forces rapid pupil dilation when shifting focus between paper and keys under fluorescent lighting. Pure black = max contrast strain. Pure white = direct glare. Solution: matte beige with controlled reflectance in a narrow band to minimize eye fatigue.
Global adoption happened because IBM and Apple wanted single SKUs for all markets. Beige also hid fingerprints and manufacturing defects better than any other color—practical engineering win.
Ironically, modern RGB keyboards reintroduce the exact eye strain problem DIN rules solved 40 years ago.
The IBM Model F with buckling springs remains the peak of keyboard over-engineering—better than even the Model M.
