Not sure if it fits here, but i finally managed to make a MT4 complete dark mode. Just follow the instructions here:
It's not perfect, there is an issue with the tabs in the bottom, the rest is perfect (i think this could be solved by trying other themes). As a bonus you even get a dark mode Metaeditor that makes even a bigger difference. No more burned retinas
PS: you need the borders indicator for it to be perfect if you're using more then one window
