The fact that the web managed to embrace responsive design and utterly forget about colour is a crying shame. This extension fixes that oversight and makes the web usable in low-light situations.

Unfortunately, to do this, it needs to continually process the entire DOM, and for sites with massive amounts of information, such as big Trello boards, this is a big hit and slows down everything. As such, this shouldn't really be done as an extension: it should be part of the browser rendering pipeline.
