Any tool that can replace a specific color with another?

I’m looking for a tool that accepts a specific RGB value, lets say #004c00 (0,76,0) and change it to another, let’s say black (0,0,0). So any color values on the screen with the given values will be replaced with another one. I’m not looking for Photoshop or any kind of image editor, this need to be an application independent system wide thing.

Does any kind of tool like this exist? Are ICM profiles able to do this, and if so, how?

Thanks!
