A Pigment of Your Imagination

From the horizons of my mind to the shores of your consciousness, 

could this world be just a "pigment of the imagination"? Everything we sense filtered through our own beliefs and perceptions. Textures, shapes, tints, hues, colors... Can we ever know if the pinks, yellows, blues and greens that you see are the same as I see? Your green could be more yellow, your blue more red. So what causes this? Anatomy, physiology, neuro-chemistry? Yes. And more. I believe it has to do with the health and clarity of our body, mind and spirit and how they all work together.
