history: I love the color Red! It is so bright and vibrant! Oh, that's nice. It actually sits at the end of the spectrum of visible light. What 2 colors can you mix together to make red? I am not sure, but the red color of blood comes from the protein hemoglobin. What else can you tell me about the color red?
knowledge: Iron oxide also gives the red color to the planet Mars.
