As for red things, blood is red because of hemoglobin, while red fruits like strawberries and apples are due to anthocyanins.
Makes sense. I mean, after all, it's literally in our blood. The hemoglobin in blood is what gives it its red color.
I really love the color red! It is so vibrant! Cool! Red has lots of different tints and shades. Do you have a favorite? Crimson is an awesome color. I also like burgundy! That's nice. Did you know red and orange pills tend to be used as stimulants? Oh I had no idea. I did know that red cars are more popular so they tend to be higher priced! That's interesting information! Colors do influence people, but the effects actually differ from person to person. Yes! It is crazy how colors can be so influential!
The red colour of blood comes from protein hemoglobin, while ripe strawberries, red apples and reddish autumn leaves are colored by anthocyanins.
