"Blood!!" screamed Christine. "Blood!!"
It was Agnes's terrible fate to keep her head in a crisis. She sniffed her finger again.
"It's turpentine," said Agnes. "Er. Sorry. Is that wrong?"
This is when a spillage of some innocent red substance is mistaken for blood. This substance is, more often than not, ketchup, and Hilarity Ensues most of the time. This is, however, occasionally used seriously when someone is trying to fake an injury.
Someone may or may not dip their finger in it and taste it, much to everyone else's horror, and pronounce it as being 'tasty.'
It's also worth noting that ketchup looks absolutely nothing like blood, apart from its colour. Smelling like spaghetti sauce rather than an abattoir is also a bit of a clue. The gag specifically involving ketchup is more common in older works, when tomato ketchup was much thinner and runnier than it usually is today.
Compare with Symbolic Blood. Prop blood is Kensington Gore. When it really is blood, but not belonging to the splattered person, it's Not His Blood. Not to be confused with the Chunky Salsa Rule, nor with a Fallout trait/perk. See Did Not Do the Bloody Research for confusion about the rude word "bloody." See also Prank Injuries.
If it is actual blood, that's Bloody Horror.

- Full Metal Panic? Fumoffu does this with red paint in the Haunted Hospital episode. Since Chidori had just fallen through the floor and bumped her head, and the paint was splashed under her head, it was rather disturbing.

- Played with in Karin. The protagonists clean up a pool of blood and replace it with red paint, leading a vampire hunter to believe he's fallen for this trope.
- In an episode of the Kirby anime (titled either "A Midsummer Night's Scream - Part 2" or "Scare Tactics Part 2", depending on the version), several characters get trapped in an old, creepy house that wasn't there before. One of the rooms contains an odd-looking skeleton and what turns out to be a large amount of red paint. Later on, some of this paint gets dumped on King Dedede and Escargon as a prank. Even later, Dedede uses the paint to make it look like he's gotten into some serious trouble, as part of a trap (which he himself did not come up with, and objected to at first).
- Played even further in My Hero Academia, when Midoriya shows up at Gran Torino's apartment for his internship, he discovers the latter face down on his kitchen floor in a pool of blood and his intestine hanging out. It was actually a plate of ketchup and sausages. Gran Torino claimed he had made himself lunch and accidentally fell down, but considering that he's The Gadfly, it's likely he did it just to freak Midoriya out.
- One of Usopp's moves in One Piece is the "Ketchup Star" which he uses (on himself) to make the enemy think he's been fatally injured.

- Parodied in a The Far Side cartoon, with anthropomorphic bottles of ketchup (yes) are watching a horror movie. When an on-screen bottle of ketchup gets murdered, a bottle in the audience turns to his young son and says "Don't worry, son. They're just actors, and that's not real ketchup."
- Another strip featured a pair of sharks staring befuddled at a bottle of leaking ketchup, with one of them remarking: "What the? Ketchup? We followed a ketchup trail for three miles?"
- The "ketchup resembles blood in no way beyond color" bit was lampshaded in a certain FoxTrot strip where Jason accuses Paige of punching him so hard that he's coughing up blood, and "proves" it by presenting his Red Right Hand.

Jason: It could just be that my blood is naturally thick and zesty.
Andy: Just how many colas did you and Marcus drink today?

- Another Spider-Man example: In Adam Troy-Castro's Sinister Six Trilogy, Spider-Man manages to fake his death using a plate of lasagna and a shard of the window he was blasted in through. Electro is thoroughly fooled, though that isn't saying much. A bystander also reports on the phone to being a witness to the death of Spider-Man; Either he was hiding under a counter during the set-up or was faking it for Spidey's benefit.
- In the Gravity Falls fanfic Angle of Impact, Stan steps outside to where Dipper and Mabel are playing paintball, gets hit by a stray red paintball, and thinks he's been shot. It later turns out that this is not the first time this has happened, and Soos threw out all the red paintballs specifically to defy this trope; hence why the only red ones available were ones that Mabel made herself.
- Zigzagged in The Simpsons fanfiction Part of the Flander's (sic) Flock. The Simpson kids are staying with their neighbors the Flanderses and are watching Itchy and Scratchy (an extremely violent parody of Tom and Jerry).

- This occurs in Despicable Me, when one of the orphans gets trapped in an iron maiden, and a red liquid is seen flowing out the bottom. Turns out one of the spikes punctured her juice box.
- A deleted intro in The Incredibles has the Parr family attending a neighborhood picnic. While Bob Parr chops up some steaks, a person screams that Bob has chopped off his fingers.

- Cloud Atlas: Frobisher does his best to avoid making a mess, but it leads to this trope regardless in the film, when Sixsmith clings to his lifeless body.
- Done with a combination of ketchup and actual blood in Cornered!
- Played with a little in Eternal Sunshine of the Spotless Mind. Jim Carrey uses a ketchup packet to "slit" his throat; the motion is so sudden and Carrey's face so grotesque (and the movie itself so weird) that the audience often jumps, thinking he's committed some act of real violence against himself. Kate Winslet walks in, however, and is not fooled (or even amused) for even a moment.
- Also inverted in Ginger Snaps, when Ginger tells her dad that the large pool of blood on the kitchen floor is in fact syrup. To make it more convincing, she tastes it and offers him some.
- Used to great dramatic effect in the "Beat" Takeshi vehicle Hana-Bi (Fireworks).

- Happens with a red slushee on a windshield in Pineapple Express. Looks convincing enough that it had to be turned black in the trailers due to the MPAA's no-blood policy for greenband trailers.

He illustrates it, with a number of red spots surrounding him, writing, "Don't worry, the red spots on this page are just jam... I hope." Later, it's revealed that he made the whole event up, so whether it was meant to be blood or jam is no longer important.
- Inverted in Dexter is Delicious: There's an obvious wall full of red stuff quite similar to blood, and Deborah wants it to be paint or animal blood in order for the feds not to take her case; for all her trouble, it seems to be human blood (although not her victim's blood type). She still argues that, if it's so much human blood, she has a murder on her hands, and so it's her case.
