SubjectRFE: tty color features
Date
(This is not a complete spec, only a sketch.)

It would be nice to be able to specify fg/bg colors at the tty level, so that echoed characters can be colorized. Then your shell can arrange that shell command input is one fg/bg color, and other input taken by commands run from the shell is another color.

For example, like this:

stty color-echo=#ffdddd/#000022 color-out=#ddffdd color-err=/#220000
stty color-fd3=/#222255
stty color-out=

or

stty color-type=cmd:#ffdddd/#000000
stty color-echo=cmd
echo foo
stty color-echo=#eeeeee
echo bar
stty color-echo=cmd
echo baz

Names of things that can be colorized might include:
echo
out
err
fd0
fd1
fd2
...

I think named colors should be supported, with at least these builtin names:
echo-default
in-default
out-default
This
stty color-type=echo-default:
tells the tty driver that echo-default does no colorizing.

I used #xxxxxx notation as a placeholder. Probably in actual use, the user would supply a terminal escape sequence.

Typeahead is tricky:

stty color-typeahead=#ff6666/004444

This would cause typeahead to be echoed in the desired color, and then when appropriate, typeahead characters could change color, such as when they are consumed or when they are hanging there with a pending cooked read.
