Also, here's a fun little test that shows how well you can distinguish between colors. Also pay attention as you move a block, how it appears to "change color" in relation to its neighboring colors. For example as you slide the block to a new position it may appear warmer or cooler. We will talk about color temperature in class and this is a great way to see how relative color temperature is!
