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.
This topic was also one of my favorites. I think it is so interesting how we can perceive so many different shades of color. Just looking out the window we can see several different shades of green in all of the different plants. It is truely fascinating that just by mixing two colors together we can expand color by so much.
ReplyDeleteI think that we are very fortunate to have evolved trichromacy. Some animals only have two types of cones, and are limited in their ability to see color. While some animals actually have 4 types of cones, like chickens, researchers find that this fourth color helps little in the ability to distinguish color. I can't imagine what it must be like not to distinguish all of the beautiful colors of the rainbow. I have a new appreciation for colorblind individuals. Although most are still able to see color, they have a greater difficulty in distinguishing some colors from others. Objects that are different colors may look the same to an individual who is colorblind.
ReplyDeleteThe following picture represents the different kinds of colorblindness:

Olivia - very interesting post. I'd love to see a study done based on how chickens interpret color differently, granted it would be tough to have a chicken properly convey the color differences. Your link on different types of color blindness is something I've never seen before - it's fascinating how the body compensates for the lack of color with color replacement, such as the red stripes on the flag looking green to someone with red color blindness.
ReplyDeleteIt is interestingh how color is really how we indentify a lot of objects. Do you remember when heinz ketchup came out with purple, green, and blue ketchup? I absolutely could not eat it. I knew it was ketchup and I knew it tasted exactly the same as red ketchup but for some reason the change in color made me think it was something else.
