OK. There's a new and very interesting CoolReader version 0.0.6-1 with CREngine 3.0.49-16. It has a new option in 'Settings' of 'Gamma Correction', which makes texts to appear with more—or less—contrast. Lower numbers give more contrast (or blackness) to texts, and it works very well!

There're 2 different versions (quoting pkbo): "'standard smoothing' and 'smoothing the soft' (soft smoothing applied to an 8-bit mode of formation of the text)'.
A list of changes: updated kernel version, added an optional parameter font rendering gamma, fixed the formatting of text in terms of appearance in the early pages of traces of predydnschey line."

The zip files has only the CoolReader app, so just replace the cr3-pb.app in \system\bin if you have already installed the previous version 0.0.6-1. I'm using the standard smoothing version and it works very nicely.
