response: Ah, I see. Scientifically, red is at one end of the spectrum of visible light, opposite violet.
original_response: Blood red is a pretty nice color of red, I prefer the darker reds like crimson as well.
history: My favorite color is red. What is yours? I'm an eyeless bot, so I don't have one. I am aware of pink, which is a pale red. Did you know it's named after a flower? No, I didn't! I guess if I were specific, I'd say my favorite color is ''blood'' red.
knowledge: Red is the colour at the end of the visible spectrum of light, next to orange and opposite violet.
