The Tk toolkit allows color to be controlled with X resource database
settings.
The app-defaults-color file defines a grey family for the Tk
widget set that provides a nice background for the color highlights
used by exmh.
Some colors are named symbolically.
For others, hexadecimal numbers specify the red, green, and blue
components of the colors, with two hex digits for each component.
A family of greys are defined -- ranging from light grey, #efefef,
to a 50% grey, #7f7f7f.
The basic widget settings are shown below.

The background of a button when the mouse is over it.

Hint:
If you use a monochrome screen and want reverse video,
put the following resource definitions in your ~/.exmh-defaults-mono
file:
*Background: black
*Foreground: white
*c_background: black
*c_foreground: white
The remaining resources are special resources introduced by
exmh that define the color highlights.
These resources control the appearance of the table of contents and
folder label display.
The trailing Bg or Fg in some resource names is purely
historical accident.
Originally you could specify only the foreground (for current
and unseen) or the background (for moved and deleted).
Now, for the benefit of users with greyscale monitors,
you can specify all of them.
The fdispColor.tcl and ftocColor.tcl
files have good examples of the use of these resources.
