Chris. Maybe not what you may think of as a decent solution but you might like to try Night Vision Saver – free download from http://davesastrotools.weebly.com which floats a window that simulates a red rubilith over all or a selected part of your screen. It's not perfect in that you can't immediately access other windows underneath it but it can help if you only want to cover largely inactive windows or you don't mind moving it out of the way from time to time as needed
