patch 9.1.0061: UX of visual highlighting can be improved
Problem: UX of visual highlighting can be improved
Solution: Improve readibility of visual highlighting,
by setting better foreground and background
colors
The default visual highlighting currently is nice in that it overlays
the actual syntax highlighting by using a separate distinct background
color.
However, this can cause hard to read text, because the contrast
between the actual syntax element and the background color is way too
low. That is an issue, that has been bothering colorschemes authors for
quite some time so much, that they are defining the Visual highlighting
group to use a separate foreground and background color, so that the
syntax highlighting vanishes, but the text remains readable (ref:
vim/colorschemes#250)
So this is an attempt to perform the same fix for the default Visual
highlighting and just use a default foreground and background color
instead of using reverse.
I also removed the hard-coded changes to the Visual highlighting in
init_highlight. It's not quite clear to me, why those were there and not
added directly to the highlighting_init_<dark|light> struct.
closes: #13663
