Although i like this theme very much, it's quite hard for me to read it. Especially when a post has a lot of text.
I'm colorblind so maybe i'm one of the few who has problems with this?
But i would like to see another lighter theme to choose from (and keep this the main theme of course).
Now i also know that can be quite some work (although the CSS file is quite compact at least), i could provide help with this if needed.
Just my 2 cents, thanks.
