> Amber/orangeish text always felt more soothing and pleasant, but on the other hand, green texts felt more readable (ie texts were easier to comprehend), although I couldn't explain why.
The human eye has "better resolution" for green light (vs red and blue). It's also why the Bayer pattern array has twice the ammount of green elements vs red (or blue).
Not just resolution, but overall sensitivity as well - meaning that green light of the same intensity looks brighter. This is also why most night vision devices use green phosphor, why some flashlights have a green LED (less energy for the same perceived brightness -> more battery life), and why green lasers for pointing/marking are increasingly common.
Since black is the same black in both cases, a green CRT will therefore has a higher perceived contrast.
