Is it possible to tint an image with a specific color using CSS without an overlay in a WebKit browser?

While there are no stand alone tint filter you can make kind of one by composition of existing filters without shading.
Combine sepia to unify the color, then hue-rotate to the color you want it to be tinted with
-webkit-filter: sepia(90%) hue-rotate(90deg);
I use borders with an alpha value for my tints, its really an overlay but doesn't use any extra DOM elements making the transition to sepia+hue-rotate simpler when the other browsers get those filters.
