GOOGLE, WHAT HAVE YOU DONE?!

Why does Google seem to insist on moving to using barely distinguishable colors to indicate read and unread emails? I've noticed this on both Android and the new Gmail look now.

At first I thought it was just the Android team that was being stupid with making the Gmail client use barely indistinguishable colors for read and unread emails. But I just tested the new Gmail look with my junk account and what. the. fuck. No matter what theme you use they're barely distinguishable and on the default theme they might as well be identical.

Seriously, why does Google seem to think this is a desirable thing to do Gmail?
