The way to lock the colormap for a particular window using OLWM is to press
the colormap lock key with the pointer over the window whose colormap
you want to use.  The default key sequence for this is Control+L2 (for those
with Sun keyboards).  The window will retain the  "color focus" for as long
as it exists, or until you lock in another window's colormap, or you unlock
the colormap by pressing the color unlock key (Control+L4 by default.)

The resources used to control colormaps are:

OpenWindows.ColorLockKey (default "Control L2") is the key sequence to lock
in a window's colormap.
OpenWindows.ColorUnlockKey (default "Control L4") is the key sequence to 
unlock the colormap.
OpenWindows.ColorFocusLocked (default "False") allows you to set OLWM to
run in an mwm-like way.  I don't use this option, so I don't recall exactly
what it does.
