Subject: tests/color: Use /dev/tty over $TTY

$TTY is the actual TTY, e.g. /dev/pts/3, which may not be accessible by
the current user.  This can happen e.g. if the PTY is owned by root, who
then does

    root@host# su user
    user@host$ ./tests/tests.sh
    ./tests/color.sh: line 81: /dev/pts/3: Permission denied
