Ok that is exactly what they said, blue, neon blue.
Wow - noticeable at least!

Which makes a lot more sense, since dyes can only darken right? You can turn white fat blue, while red muscle would at most turn a somewhat darker purple which might not be so obvious?
The blue is sufficient but not necessary for the animal to be impacted by the poison. It is a very vibrant blue though, and anyone would be concerned if they opened an animal and saw that.
> Diphenadione is a vitamin K antagonist that has anticoagulant effects and is used as a rodenticide against rats, mice, voles, ground squirrels and other rodents. The chemical compound is an anti-coagulant with active half-life longer than warfarin and other synthetic 1,3-indandione anticoagulants.[3][4] ... Rat poisons with diphacinone are often dyed bright blue to signal toxicity.[8]
While I don't think the average person is going to notice or care about these "nuances" I would be pretty surprised if anyone that huts would not immediately notice. The "well I look at my veins and they are blue" argument only holds up if you don't look at the pictures in the link. Like they just look very different. Easy to sound right while being very wrong (and often hard to explain why it is wrong without sounding like nitpicking). It's not like they're hunting horseshoe crabs...

[1] Pale enough that a phlebotomist once told me I was the easiest person to draw blood from because it is so easy to see my veins.
The reason anything is the color it is is because that’s how it appears.
Am I missing something?
It’s like saying, “oh the sky is only blue because it scatters blue light”. Well then the sky is blue. Full stop.
“Red paint is only red because it happens to absorb certain other color spectrums leaving mostly red light”. Ok then it’s red.
> Am I missing something?
Now yes, the sky will be yellow or whatever color the plastic is but if you go around and start telling everyone that they'll call you crazy.
If you really want to get into it, colors are also determined by what everyone else sees. You could be colorblind and what color something is to you is not what color that thing is to everybody else. Or you could take the sun itself, which everyone agrees is yellow except some armchair expert redditor who once heard in science class that "the sun is green" and is willing to discount his eyes rather than hear the rest of the discussion where it is white because it emits in a broad spectrum and appears yellow on Earth because the blue sky removes some colors before we can see it. So you can imagine a future civilization where most people don't live on Earth might call the sun "white" but for now everyone will call it that because it is yellow. This is a bit in your favor but you might notice the main point of my previous comment isn't about blood looking blue so much as the pigs being fucking neon blue and that blue looks nothing like blood and could not be mistaken for the same thing. Look at the pictures.
Huh, thanks.
Eyes can't be blue either.
> Eyes can't be blue either.
The blue in blue eyes (and green) is a structural property, not a pigment property. This is also why eye color changes for these people much more dramatically than people with darker colored eyes (see Hazel eyes).
It's color caused by structure, but that doesn't make it not a color. A lot of things aren't going to "have color" if you use that definition. Including the sky...
Like when rich people consumed food and beverages from pure silver plates (100's of years ago) their blood supposedly turned purple/blueish. Hence the term (at least in Dutch) that "he is of blue blood" = he rich af.
Or that's all a myth. Not sure.
This is usually said to refer to the fact that someone's skin is so pale you can see the veins through it.
(Also, it refers to pedigree rather than wealth, in English...)
I would expect silver to turn things black, not blue.

Have you eveer seen a blueberry? Or a Concord grape? Or a damson plum?
