We
all know that colors do change under different illumination; however, colors
still remain relatively constant. While the color of someone’s blue shirt may
appear slightly different indoors then it does outdoors, a person can still
tell that the shirt is blue. Even with the changes in wavelengths of light from
the sun and light from artificial light, color still remains fairly constant.
Chromatic adaption, prolonged exposure to chromatic color, is one reason for
the consistency. When you walk into a room with a bright light, your eyes adapt
and become less sensitive to the rich light. Memory also helps with color
constancy. A person’s knowledge of the usual colors of things in the
environment allows them to perceive things with richer color. Objects such as a
red stop sign or a green tree may seem richer in color than unknown objects.
I found
this color illusion on youtube. If you continue to stare at the dot in the
middle of the screen, the castle appears to be in color. If take your eyes off
the dot at any point, you will see that the castle is actually still in black
and white.
I've seen this illusion before! It was great to finally understand why this was happening. The first time I saw it, my mind was blown.
ReplyDeleteI thought that your post can a lot of interesting facts to it. I thought it was interesting that memory helps a person recognize color and knowledge as well.
ReplyDeleteI loved the video link you added. It is so fascinating. There is so much that goes along wit the perception of color and you picked a great and interesting topic. Isn't it crazy how many aspects there are when it comes to how we perceive color?
