One of my favorite topics that we learned about in the textbook was color. Color is very helpful in many ways to us. We can recognize different objects by its color and color makes it easier for us to distinguish what we are looking at. I thought it was interesting when the researchers showed a group of people a purple banana and they didn’t recognize it as fast. I found it interesting that researchers consider the basic colors to be red, blue, yellow, and green. While looking at the color septum I thought it was interesting how only a few colors are actually there, but you can see other colors when you mix two together. In fact, the book states that there could be up to 200 different colors there. I love learning about the meaning of color. It has many functions and purposes in life. It is not only a beauty but it also helps us identify different objects. Color keeps things organized and in order. Color does not only help humans but animals as well. Color helps them find food and other resources. Colors have different meanings. For example, some colors are popular in different cultures. Colors also stand for signals. For example, a green traffic light means go, while red means stop. We can associate all different types of colors with different meanings.
