One of the main issues since upgrade from 4.1 to 4.2 is not liking the faded text.
The standard text in posts has been faded, and it's not gone down well. In 4.2 text went from #272A34 to #353C41.
In activity expanded view https://invisioncommunity.com/discover/unread/?&view=expanded there were complaints that it is hard to read the latest posts. See how the actual post text is lighter and not as easy to read? Text went from to #272A34 to #555 in this case, an even bigger jump. It also isn't helped by the above line (example. sweethoney replied to Luc Wolfe's topic in Product Guidance) is bigger and darker than the post, whereas previously it has the ipstype_light setting, and was much lighter and so the post content stood out more.
I have reverted these instances on my site but I'm interested to hear the reasoning behind these changes.
