Please better distinguish between PREVIEW and the actual BODY we type in

I'm probably not the first person to get screwed over by this. Especially, say...if while scrolling through a massive post you just made, you accidentally mistook your preview for the actual body while proofreading, and then instead of deleting an error with backspace, you went back instead, undoing all your typing. Make the Body section your standard MSword-like white background with black letters. Not this ugly dark-blue with peach/orange/yellow-lettering. If you want to keep it this way, fine, do it for actual posts. But if people are typing their own post, give them an option to just make it standard black and white. Or anything to better distinguish BODY from PREVIEW, or have an in-built system that saves what you're typing in case you accidentally backspace, or worse, accidentally brush your mouse across one of the tabs at the top of your website (Game Infor, News, Competitive, etc.) and click on one of those links instead.

On a side note, if people pastes a URL for an image, let them see how the image looks in the PREVIEW just like how it'd look when the post actually gets posted. That is, what the entire point of the preview right?
