This option controls whether or not to force bold text to use colors
from the ExtendedPalatte.
If True, then colored bold text will always use colors
from the ExtendedPalatte. There will be no way to print bold
text colored with the BasicPalatte.
This often isn't a big problem, since many TUI applications use bold
in combination with colors from the ExtendedPalatte. Also, the
VTE default blue color can be difficult to read with a dark
background, and enabling this can work around the problem. See
https://github.com/cdepillabout/termonad/issues/177 for more
information.
If False, then bold can be applied separately to colors from
both the BasicPalatte and ExtendedPalatte.
