A piece of white cloth actually has many different colors intertwined on it, such as red, yellow, orange, green, blue, purple... Standing far away, it is still a piece of white cloth, and the optic nerve automatically adjusts the picture.
Memory is actually very similar to the optic nerve. Those memories of happiness, pain, joy and sadness, now seem like that.
