There are some other interesting effects if watching a spinning wheel made of black and white spokes, some people see colour flashes at certain speeds where the cones are tricked into firing instead of the rods. But I've never seen the wheel spin backwards in natural light.
rods are not used in bright light. They are using the yellow, green and violet cones together. the concept of brightness is a combination between the three, and the chroma is found by subtraction, resulting in something fairly equivalent to YUV.
