Right, and red sky at morning, sailors take warning.
My husbands favorite color is red.  do you like that color? I can't see because I'm a bot. That said, I do know that red has a range of shades from yellowish scarlet to bluish crimson, and from pale pink to dark burgundy. Scarlet and grey is Ohio State colors which is why my husband loves red so much! Oh, the color of blood comes from hemoglobin, but strawberries and red apples are colored by anthocyanins. wow that is interesting. Also, red pigment derived from ochre was used in prehistoric art. Wow that is really interesting I didn't know that.  The color red has a lot of history with it then And from a more science-y topic, the red in sunsets is due to Rayleigh scattering. There's a saying, "Red sky at night, sailor's delight".
