The uxterm's color is set from Xresources.

	UXTerm.vt100.foreground: gray66
	UXTerm.vt100.background: darkslateblue

and then tty color is disabled using

	(defun x/tty-color-mode-no ()
	  "Disable color in emacsclient session."
	  (interactive)
	  (set-frame-parameter nil 'tty-color-mode 'no))

evaluating

        (set-face-attribute 'default nil :background "red")

has no effect on the uxterm/emacsclient but changes to red background
the other emacs windowframes sharing this session.
