It might be rather easy to make that work
on a terminal with lots of gradations of color.
The main hard part would be to know how much change is needed
for users to see it clearly.

However, on a tty with a limited set of colors it could be impossible.
If a mode depends on this to work in order to make the output comprehensible,
it would fail totally.
