This lesson we explored deeper into the human sense of sight, particularly color. Color is a a part of our vision enabled by the cone cells in the back of our retinas. These allow us to to distinguish details in the light that is reflected back to our eyes. By being able to see parts of the visual spectrum, we can garner more details and information from our vision and are better able to distinguish similarities and differences. As was seen in the Vsauce video, electronics are able to adjust their LED output to match wavelengths, which allows our brains to see a certain hue of color and witness the full scope of our visual sense in an electronic device.
However, our sense of sight can be deceived since our brain processes color based off of a system. If we are able to use that in a certain way or alter its exposure, we can trick it into distinguishing things that are not actually real. This was seen in the printed image video and the ocular illusion one. The printed images reflected the the exact wavelengths to trick the brain into perceiving a sense of volume and depth which we are regularly exposed to with 3D objects in our every day lives. The ocular illusion video set up color in a way that our brain was fooled into perceiving movement or another image at a second glance.
The final video shown was the TED talk where probably the most was explained in terms of color (how it helps us and how it can be deceived). He explained how it allows us to detect things and its relation to other senses (ie. sound). He also explained how context was important for our vision and how it makes clarity of the visual information we receive to provide us with a means of interacting with our physical world.
This image is the classic '2 faces or 1 chalice' optical illusion where shifting the color of the context allows us to see 2 different items. It provides insight into the way our brain works to distinguish things depending on their surroundings.
