I'm getting some complaints (off the forum) that some of the darker grey text is nearly invisible on some monitors. On both my monitors its fine, and I suggested to those who had issues to try adjusting the contrast/brightness of their monitors so they can see all the grey shades on this chart:
you should be able to clearly see all the steps in the middle strip and they should look like even steps. ideally you can just make out that the '1' is darker/lighter than the '0' on the top and bottom chart. many monitors come from the factory with the brightness and contrast set WAY too high, and this saturates whites and leaves dark greys nearly invisible.
