While I'm currently not updating my comic site, and any INK sharing isn't installed yet, I was wondering how much of a faux pas it would be to use CSS to grayscale the INK comic banners. It's entirely an aesthetic thing; my website is all sepia and grayscale itself.

I would be completely cool with voiding any benefits I get from displaying other INK comics and just use it to help people find other ones. I'm just wondering how permissible that would be, with any sort of tweaks if necessary: color returning on mouseover, preferential top-of-page placement, or just restricting the advertising to comics that are similarly only in grayscale.
