As can be seen in the logo of this page, I have some nostalgia about this. The other mode I have met was black, red, dark yellow/brown and green. The clasical mode comprises black, cyan, magenta and white and has become a legend. We were all stunt with the “new” 4 color modes. Till the day all changed: someone brought a PC that was CGA capable. When I was a kid, I took a couple of computer courses and, on those days, all was green phosphorus monitors or gray scale ones.
