Blue is the color of light/abundance/energy arriving (the light from stars approaching earth shift to blue). When the sun rises, the hues are shifted toward blue. Red is the color of light/abundance/energy departing (the light from stars moving away from earth shift to red). When the sun sets, the hues are shifted toward red.

Our hearts appear to invert this paradigm, for within them, blue (entering the left side of the heart from the body and moving to the lungs) indicates oxygen/abundance/energy departing and red (entering the heart from the lungs and exiting the right side of the heart to the body) indicates oxygen/abundance/energy arriving.

Unless the Earth — and/or our position as perceivers is analogous to a heart-lung, in which case, the paradigm is preserved, but the meaning of the light model is transformed… not to mention the identity of our world and participation in it…
