Do you like red, it's my favorite color!
I can't see because I'm a bot, but my knowledge of red is that it's at one end of the spectrum of visible light, opposite violet.
It's just before infrared, right?
I actually don't know, but its dominant wavelength is 625-740 nanometers.
It's interesting that we can assign numerical values to colors.
The planet Mars looks red because of iron oxide.
