Colors

So I was watching a video about how people see colors and I realized that they were right. The video says that there is no way to determine if the color I see is the same color you see on an object. This got me thinking about just how much the color could vary from person to person. How could we ever know if the sky looks like the same blue, if we were able to describe the color to each other would your description sound like the color yellow to me where as my description might sound like the color red to you. If you would like to check out the video here is the link:

IT is by Vsauce and they have some really good videos that make you think about things differently.
