4 months back I started making an extension named monochromate which was basically a greyscale extension, I realised power of them when I turned it on my phone and the thing is being a programmer most of my time is spent on browsers ... and that's where it don't exist (at least not the perfect solution for my needs).

That's how I came up with it, made it open source, recently passed 100 users over chrome webstore and it have 5-star rating as of now.

and yes you might say that why would I need it when I can do this with filters that can be toggled via settings, thing is I didn't wanted to greyscale my work sites as well and thus I made site exclusion, also have scheduler, intensity control and above that all it supports all the browsers including Firefox providing same experience.

Would love any kind of feedback over this!!
