Deleted answers to questions are very difficult to tell apart from regular answers - the color difference is very small and easy to miss.
Color code is #F4EAEA, i think something slightly darker like #EAA4A4 might work better.
#EAA4A4 seems too jarring - it almost emphasizes deleted content when it should really be downplayed a bit.
Having said that, I agree that the existing color is a bit too light. Starting next build, we'll use the same deleted content background color here as we do on Stack Overflow. It should be easier to tell apart.
