I am using this theme on my main site for many years now. But was always wondering what is the reason for having this lighter shade of gray for text? Just like this forum pages for example.
As an example of (perhaps) correct text color I might think we can use Face Book. As far as I can see Face Book, text colour, for example for messages is rgb(20,24,35). That, I find very readable and pleasant.
Theme Horse team seams to like somewhat lighter text color rgb(119,119,119). Which I find sometimes difficult to read or even irritating.
