I've been messing around (pun sort of intended) with WAM artwork in Inkscape lately and uploading the results.
This particular concept started out as a wedding clipart-style image with added gunge, with the happy couple enjoying their first married kiss beneath a torrent of coloured slime.
For my first go at it, it seemed most obvious to give the bride pink gunge and the groom blue (version 1), but then I thought stuff gender stereotypes and did it again with the colours switched (version 2). Then, since it is now 2015 and marriage is finally for everyone in most places, I did versions featuring female and male couples (versions 3 and 4 respectively).
