The most egregious example is old CGA games that were written to work on composite monitors. Without the composite display, they appear monochrome or cyan and magenta.

It blew my mind when I finally learnt this, as I spent years of my childhood playing games that looked like the examples on the left, not realising the colours were due to the RGB monitor I had.

Oh you’re blowing my mind right now, played lots of CGA games with neon colours as a kid. What did they look like on a composite monitor?

Also, are you able to tell me the name of the game in the second row in that screenshot?
