Module 3

1) In the video, we learn that humans have emotional responses to color. Blue and yellow are colors that we have learned earlier on than colors such as red and green. This means that we have evolutionary responses to these colors which are "hard-wired" into our brains, such as that of the calming effect which blue has on humans. It is believed that because humans evolved from single-celled organisms that lived in water and used energy from the sun, we have had the ability to see blue and yellow for longer. However, the emotions or reactions we have to red and green are simply a function of the cerebral cortex which we developed much later on in the evolutionary process. The correlation between color and emotion is evidenced by the experiment conducted in which those placed in a state of feeling powerful were more effectively able to detect changes in colors than those placed in a state of powerlessness. 

2) Color constancy is an intriguing concept which describes how we should perceive color relatively similarly despite varying effects of light. This is because our eyes do not "see" color, but rather our brains draw on knowledge of what an object's color should look like.

3) I was very interested to learn that we may have deep feelings attached to the colors yellow and blue because of evolution. It's interesting to know that those are the first colors which humans were able to detect and therefore can have the strongest reactionary value.
