[Plugin: WP Favicons plugin] Feature Request

Great little plugin!
However, quite a few Favicons don’t “mesh” well with certain themes (namely, those that don’t have a white background).

Although it might be too much to ask to have some sort of “tint” on each favicon, would it be possible to have the plugin load a locally-stored copy of a favicon with certain URLs?

(That way someone could “tint” the cache of favicons and force the plugin to use those)
