Simple experiment. A hula hoop around your head, with a coloured bead

That would be a couple of degrees then as rods don't detect colour only
cones do that and they are in the centre of your field of view.
Any colour you see in the peripheral field is just made up by your brain.

Hmm. My brain has just made up the blue colour of a folder about 45deg.

I like to claim good peripheral vision but 200deg. is only *something
