Making the green one red.
One way to show Ludicrous Gibs without breaking the laws of biology is to have a character die in a body of water, thus diluting the blood and causing it to billow out in clouds. As a bonus, this tends to look very symbolic... of nothing in particular. Perhaps it stems from the Primal Fear of blood in general, and the illusion that there's more blood than there really is.
Of course, if this happens in the open sea, the probability that someone will mention sharks, and their ability to smell a single red blood cell from 6 million light years away, rapidly approaches 1.note
In a case of Reality Is Unrealistic, real blood diluted in a large volume of water will actually turn it yellow, the color of blood plasma (the liquid portion of the blood), not pink/red. However, the picture above is accurate in regards to relatively small amounts of water (or relatively large amounts of blood).
A related phenomenon above the waterline is Pink Mist. Can be a symptom of Gorn. A Bath Suicide or Deadly Bath is likely to invoke this. Common in Toilet Horror. Often overlaps with Symbolic Serene Submersion.
Compare Blood Bath, where circumstances see blood substituted for water.

- Whenever the shark kills someone underwater in Jaws Unleashed during the cutscenes, it turns a big area in the water blood red.
- MadWorld takes this trope Up to Eleven (as it does with just about everything) in the Courtyard, where there is a fountain in the center of the first part of the level.

See it here.
- In World of Warcraft, if you kill a beast in the Borean Tundra, you find yourself covered with blood (which will piss off the local Animal Wrongs Group). You can wash it off by swimming in water, which will leave behind a "pool of blood." Repeatable fishing quests require you to do this deliberately because the blood attracts a unique type of fish.
- Truth in Television in that people who are sensitive to seeing blood will often do fine until they go to wash the wound and see the red spatters in the sink. The same can apply to people who don't feel as much pain from minor cuts until they see the injury.
- Similarly, cutting yourself in a swimming pool can be a harrowing experience.
- Or having your gums bleed while brushing your teeth. Sink looks like a murder scene. The worst is after getting your wisdom teeth removed, the holes will often bleed profusely, resulting in spitting huge mouthfuls of blood into the sink.
- Or getting your period unexpectedly in the tub/pool/ocean/what-have-you. Even going to the bathroom while you're on it can produce this effect.
- When doctors are treating people who have cut themselves badly and ask them to estimate how much blood they've lost, they take this trope into account, knowing that people who have bled into water are likely to grossly overestimate.

- There was an incident at Sea World where an orca attacked another orca during a show. The pictures are horrifying.
- The Cove, a documentary about secret dolphin killing in a town in Japan. At one point there's an underwater camera, which seems like it serves no purpose other than to look into the very clear water at the bottom of the cove. A few seconds later, the entire view of the camera turns a bright, opaque red from the top down due to the quantity of blood in the water.
- When the toilet gets clogged as a result of someone flushing their menstrual products down the toilet instead of properly throwing them away.
