you try using css filters however, don't think there filter specific colour , browser compatibility limited. https://developer.mozilla.org/en/docs/web/css/filter

alternatively use svg image allows modify parts of image using css think svg files can pretty big large images... think can use adobe illustrator save files svg. http://www.w3schools.com/svg/tryit.asp?filename=trysvg_myfirst
