Thank you @silvadori for hunting my CSS Library!
So, this idea came to me while I wad attending the DotCSS 2015 conference in paris, during the talk of the talented @una, which created ( and was actually presenting on stage ) a similar library, called cssGram ( cool stuff over here : http://una.im/CSSgram/ ).
Since I spent a part of 2015 experimenting CSS blend-modes, and I loved the advertising campaign of Spotify for 2015 too, I thought it could be a cool project to start!
I've planned the creation of a polyfill, using svg and/or canvas.
I made a quick Eager app wrapper, for anyone who would like to try a live preview on their site (or who doesn't know HTML/CSS): https://eager.io/app/colofilter/...
