@19wintersp hmm okay, my problem with that is the ncurses palette seems to be completely lacking the actual r/g/b variety, for example there is no brown (and similar colors which fall in between each rgb extreme, which was shown in the VGA example. There are some dark oranges but since it's so tilted to each extreme there really is only one shade of "brown", which is still polluted with green
@Pankak The issue is the way these colours are produced: they use escape sequences, which are not likely to change and made many years ago. You will only be able to use those 256 colours, because of technical limitations of the past. You can't specify an RGB value with the escape sequence.
It looks like it uses the following colors: black, red, green, yellow, blue, magenta, cyan and white
I hope this helps!
