Something I've always been interested in is how and why blood has changed its appearance in color films from the '60s to today.

Back in the '60s-'70s blood was very unconvincing-looking to me. It almost looked like bright red paint. Nowadays it's gone to the other extreme and is often presented as very dark (almost black) in color.

Here's an interesting article noting the changes and giving lots of nice pix to highlight the changes over time.

That's long been a topic which grabs my interest. The fake looking red paint style of blood has ruined otherwise good films for me, but that wasn't as bad as our new CGI blood debacle.

It was probably bright red back in the 60s so it didn't get censored, as it was clearly fake.

I remember Frank Henenlotter saying in his commentary for Basket Case that fake blood needs to have some blue dye in it to get a more realistic look.

Does anyone think that film can be used to harness

the powers of aromatherapy? Like if you were to see certain type of image... like a hole, or a shim, does that have associative smells that can be used to harness the power of aromatherapy? Like if you see a Dracula.
