Understanding Color Perception

The video explores how humans and animals perceive colors. It begins with a fun introduction to favorite colors, explaining how the retina and cones in our eyes help us see colors. The video discusses colorblindness, explaining how it affects color perception. It also explores how animals like dogs, bees, and mantis shrimp perceive colors differently, with some seeing ultraviolet light. The video concludes with a farewell and an invitation to subscribe for more learning.
