Monitor Color Management Freeware?

I’m looking for a way to create Windows .icm files (color management profiles) so I can have more control in adjusting LCD monitor settings. Anyone know of any good freeware to do this, or information about how to edit .icm files directly in a hex editor? My goal is to develop a set of .icm files to so that a user can minimize eyestrain, “computer buzz,” and headaches and switch rapidly to views with normal or high brightness or contrast when needed for specific Blender (or other applications) tasks. I’ve done the usual web searches, but I must be missing something. Perhaps one of you has some familiarity with this area.
