36 
+For setting the decoration colors of specific windows when they're not
37 
+focused, you can use the +set_color+ command.

+*Syntax*:
40 
+------------------------------
41 
+set_color none|(<border> <background> <text>)
42 
+------------------------------
43 
+
44 
++none+ uses the default colors from +client.unfocused+, for the meaning
45 
+of +<border> <background> <text>+, see <<changing_colors>>.
