There are so many colors and so many emotions that are not named. Language is at a loss and what better way to communicate than to transpose colors on specific unnamed emotions.
Every one sees colors in a different way, if you asked 50 people to find Coca Cola red, you'd get 50 different types of red. Just as you ask 50 people how they feel on a cold grey day, you'd get 50 different answers. This possible possibilities is dedicated to naming a few of the specific emotions though colors.
This is a very specific color, and it has a very specific emotion: You've just stared at a dog for a very long time and the dog gets a kind of weird feeling about you and you can't explain that you weren't trying to intimidate it, you were just noticing it's very nice coat and imagining what it might be like to be a dog, would you really drink out of a bowl that another dog just drank out of, that would be weird.
This color is how one feels after spending 35 minutes stretching and prying a zip-tie off of one's index finger.
