Regarding the red color that the 12th Planet emits. This is due to the majority light particle that emits, a flood that to your eye or imaging equipment dominates and then becomes the color of record. It is not the only color arriving from that source. It is a particle, a light particle, operating at a certain frequency. That's all. Leaving or approaching, the same. The variation of light you note on leaving or coming pertains to accumulation of particles, as on the approach there is a tendency for an accumulation of certain particles, which bounce around and create a dominance. Upon leaving, the opposite effect is noted.
