+	The client commands control the colors of the view borders and title bars. All
+	of the client commands _require_ five color values. (The one exception is
+	**client.background** which _requires_ one color value.) If you only want to
+	specify a subset, supply default colors for all the others. Colors must be
+	defined in hex. i.e. _#rrggbb_ or _#rrggbbaa_ when including the alpha
+	channel.

+	The command tokens are:
+		**color_class**::: Specifies the view to which the colors apply.
+			**client.background**:::: The color a view will be painted, underneath the
+			client itself. This will only be visible if a client does not fully
+			cover its allocated view space. This command only requires one color. _Note_:
+			This is not currently implemented.
+			**client.focused**:::: The view that has focus.
+			**client.focused_inactive**:::: A view that has focus within its
+			container, but the container is not focused.
+			**client.placeholder**:::: Used when drawing placeholder view contents.
+			Only background and text colors are used. _Note_: This is not
+			currently implemented.
+			**client.unfocused**:::: A view that does not have focus.
+			**client.urgent**:::: A view with an urgency hint. _Note_: This is not
+			currently implemented.
+		**border**::: The border around the title bar.
+		**background**::: The background of the title bar.
+		**text**::: The text color of the title bar.
+		**indicator**::: The color used to indicate where a new view will open. In a
+		tiled container, this would paint the right border of the current view if
+		a new view would be opened to the right. _Note_: This is not currently
+		implemented.
+		**child_border**::: The border around the view itself.
