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. Wow, that's awesome!
The red colour of blood comes from protein hemoglobin, while ripe strawberries, red apples and reddish autumn leaves are colored by anthocyanins.
