@Lalop: Yeah. In that case, maybe this image is clearer? Or maybe not; I rendered it at 45 dpi but it seems your rescaling did as good a job.
The Colemak layout. Keys changed from their QWERTY positions in bold. Home position in green.
@Davkol: I ... think I disagree. To each their own I guess. As for the font, I used the proper font that should be on IBM keyboards as I researched it – but I think my MS Windows may be approximating it now. Of course, the original image has small letters in the corner of each key, but that doesn't show up well on small images and the letters positions are important here.
If anyone else than Davkol feel that the bold is too bold there are plenty of options, like blurring it and/or graying it out a little. I think it's a neat enough idea to show which keys are different from QWERTY, as that's pretty much the main point.
On the above image, I rendered it without the dark gutters and toned down the bold face a bit. Don't know how that works out.
