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).
Compare Blood Bath, where circumstances see blood substituted for water.

One of the Deathwatch Challenges is actually nailing a body on every spike on the fountain.
