If a dog salivates to a blue light and not to a yellow light, the dog is showing evidence of photophobia – a condition in which the dog doesn’t see blue light due to a problem with his/her eyesight.
This condition is called blue-yellow photophobia and is often seen in dogs who are ill or on an IV, but it can also happen in humans and it can be a very serious problem. We can only assume that the blue light in Deathloop is what caused Colt to get sick and unable to see anything other than yellow.
Also, I would like to point out that while Deathloop is a time-looper, it does not in any way represent a deliberate attempt to mimic reality. Instead, it is very much an amalgamation of things that are true about our world. For example, a dog salivates to a blue light and not to a yellow light.
There are two things that can cause the dog salivate to a blue light. He can be salivating to a blue light because he’s eating a blue food. His salivation can also be caused by an infection of the salivary gland. The second is due to a blue light in a photopic retina.
It is an optical illusion caused by a phenomenon called photopic retinal degeneration. In this case, a blue light is caused by a blue colored object, but its photopic retinal degeneration is still going on in the dog’s retina. The dog’s salivating is caused by his body’s reaction to the blue light, rather than a deliberate attempt to mimic reality.
There is a lot of talk in the medical community of dog saliva having some sort of magical healing powers. In this case, the dog salivates because it’s trying to replicate the feel of a yellow light by drinking a blue food. It’s not a coincidence that dogs saliva appears blue. At least, not in a way that we humans would ever notice.
In this case, the dogs salivating is a subconscious attempt to mimic reality. There is actually a lot of evidence that dogs are able to mimic our thoughts, emotions, and behaviors. In many cases, it is because of a particular pattern of retinal cells in our retinas. The dogs salivating is a small example of this, and we will explore the many other cases of dog saliva mimicking reality in the future.
There is a reason why we don’t see the color red. Most of us can tell the difference between a red object and any other color. To a dog, the color red may seem blue to us, but it is in fact red. The blue light produced by our retinas may be a small part of the explanation, but is not a necessary part of it.
The color blue is so much cooler than red. The blue light that our retinas produce is not the same as the red light we see. Our brains are so much smarter that we can even make the blue light not be blue to someone who has not seen it already. So, basically, the blue light is like a color that is not there, but it makes it easier to recognize the blue object as being blue.
