I have an SVG ( http://www.feingeist.io/wp-content/uploads/2015/08/Polygon_grey.svg), which I want to recolor. Initially, I wanted to achieve this by using CSS function
background-blend-mode: luminosity; background-color: #83b5da;
Unfortunately, this is not supported by quite a number of modern web browsers. The above CSS method would use the luminance information from the SVG and the color information of the CSS background parameter.
As this is not working with some browsers, I want to fall back by performing the color overlay in the SVG already. I already found the "Recolor Artwork" feature in Adobe Illustrator, but somehow I cannot achieve the desired effect. The final result (including the color overlay with #83b5da should look like this: http://www.feingeist.io/wp-content/uploads/2015/08/Header_Webseite_blau.jpg).
Any hints on how to accomplish the described goal are highly appreciated.
