In the last few classes, we have learned about people that can hear colour, people that can taste and smell colours, but what about the people who have "colour-blindness"?
Let's begin by challenging the terminology here: "colour-blindness" does not denote an actual state of blindness but rather an inability to perceive certain colours or tones. Your retinal-cones perceive colour for you and transmit the information to your brain. For some folks, that just doesn't happen the same way it does for others.
Let's quickly go to this website to learn about how different colours are perceived by different people:

Just for fun, we can go through this test that determines whether or not you can see different colours when embedded next to other colours! An important note is that "due to the fact there are so many different monitor screens displaying different colors, the accuracy of this "on-line" version of "Color Vision Testing Made Easy" is limited." Therefore this is a demonstration and not for diagnosis.
