Vacuum and freefall complicates things. In air and gravity, the skin gets tinted light bluish/grey as blood settles to the lower parts of the body, which themselves become dark and "bruised" looking. I've seen it often enough.

As for that "vacuum damage" description...won't happen. People have been killed due to sudden decompression and it didn't turn into a scene out of a horror movie. Sudden massive compression, such as failure of a pressurized hardhat diving suit at depth in the ocean, will do that, but not decompression from 1 atmosphere to vacuum.

In fact, there's a cinematic version of what would actually happen: you've seen 2001, right? The scene with Bowman getting blown out of the pod into the airlock is entirely accurate (well, he shouldn't have held his breath, but other than that...). The human body can survive decompression physically (with some relatively minor internal physical damage) just fine.
