For EpicRuler I'm using this code to get the luminance of a pixel, which I think could be used in your case too, you just have to convert the RGB part to HEX:. Source: about 2 years ago
Also, I'm using LayAuto software for window placement on a large display (split display in various sized grids - let me know if you want me to share my defaults). This is absolutely invaluable, as otherwise you spend most of your time arranging windows. Another one I've used and likes is Magnet, but it didn't allow me to customise the split and the keyboard shortcuts. Source: over 2 years ago
