I probed some colors of our previous thinner DejaVu Sans rendering, and if
you render black text, there are no black pixels in it. The darkest I could
find was (0 0 9) in RGB. Most of them where (16 16 17), (24 12 16), or even
brighter. I know that this is related to subpixel-AA but this explains my
concerns about contrast. Sure, if you render black text on white background,
you got used to not seeing black pixels at all. You can still produce a
similar effect by changing black text color to the values mentioned above. 

Best,
Marcel
