One thing I see on this site, and it's more a peave than anything. They use shades of grey or other colours that blend so well with background you almost need to highlight text to read it.

Most of the standard greys, there fine, easily read. I like the style of thr muted grey, it can look very nice done right, and with some creative flair and contrast colours. Do you need properly it's nice. 

But a few colours, just look at your post and realise. Maybe it's a good idea to make it more readable.
Maybe just use a few tones up, no need to use bright yellow.
