Issues with VT / ANSI color codes, especially on Windows/Ubuntu

[lenaschimmel]

A lot of sub-issues:

• hard to get it working on Windows
  • recommend Windows Terminal instead
  • try the os.system('') hack found on Stack Overflow
• color bar of the last genome region (after N) extends to the end of line
• sequence names are displayed black on black, thus invisible
• unimportant stuff has much too much contrast, at least on Ubuntu (bright white)
• need more unique colors when using --force-all-parents together with --clades all (at least 17 instead of currently 6)
• Default colors for 2-parent-recombinants are red and green, making it unusable for users with red–green color blindness (up to 8% of users with a single X chromosome)

OMG, it's hard or even impossible to choose a color schema which:

• does not rely on distinguishing red/green for the most common comparison
• uses only the six (!) existing actual colors (not counting black, white and grey)
• works on black and on white backgrounds
• works with the different way that terminals interpret the colors:

Possible ways out of it:

• use 8 bit colors, which are not supported by all terminals which support color at all
• use 24 bit colos which are supported by even less terminals
• make user-selectable color schemes
• tell users to use a specific background color
• tell users to use a specific terminal
• set background color from the script
• switch from terminal to a proper native GUI or web interface
• just ignore it and accept that it won't be nice

Any ideas?
