if one's feeling determined and creative there's the possibility to render the link to a canvas and get pixel colors

Links in images are always rendered as unvisited. See https://output.jsbin.com/wowalokusa, the first is an HTML link, the second is a link in an SVG, the third is a link in an SVG in an image.

IIRC rendering the html to a canvas is done with a empty history, so all links will look unvisited.

I believe if you can do this, it would be considered an exploit. You're not supposed to be able to.

yep, it seems I was mistaken, rendering links to SVG/Canvas wouldn't work
