The Light, The Heat- Redshift, Blueshift, (Ultra)violet, (Infra)red

I was just thinking about blue and red, specifically blue and red shifts. A blue shift occurs when a perspective moves closer to a light source, a red shift occurs when a perspective moves away; this shift moves the light along the color spectrum in the direction in the name (ie orange can become yellow when blueshifted, as the encountered light moves toward blue on the color spectrum, when the light and observing perspective are moving toward each other). I don't think this can be called illusion either, it's not a trick of the eye or something, it is an actual change in how the EM wave moves (frequency/wavelength), in relation to the observing perspective. A similar and more easily conceived of effect is a motorcycle passing you, sounding higher pitched when approaching, and lower pitched when departing, also known as the Doppler Effect.

Today I was thinking about these effects at the edge of the visual spectrum. It would be possible to see something normally invisible by this relative motion. If you moved quickly toward an infrared source, for example, the blue shift would actually make it visible, appearing red. If you moved quickly away from an ultraviolet source, the red shift would then make it appear violet. In each case the source would go from invisible to the human eye to visible, through this relative motion.

I am also now considering the temperature changes in relation to these shifts. Infrared generates more heat than red light. Since this shift is an actual change in the composition of the light from your perspective, and not an optical illusion, would this also mean that moving quickly toward an infrared light source would make the light less hot from your perspective? This feels counterintuitive from an overall perspective, and it could be that other factors are involved like when moving toward an infrared source you would encounter more units of red light in each moment, which each add an overall greater amount of heat to your perspective per unit of time, even though each unit conveyed less heat. In the instance of encountering a single infrared photon at high approaching speed though, would moving rapidly toward it actually make it cooler from your perspective, when you encountered it? Compare this to the heat transfer of colliding atoms, the faster they collide, the greater the heat produced; this energy transfer is similar to a cue ball striking another ball- more energy input generally means more energy output, including heat energy. So what is it about light in this part of the spectrum that reverses this effect, with a fast approach resulting in a lower heat/energy transfer? What is more interesting still is that radio waves do not produce nearly as much heat as infrared, but if blueshifted to infrared they would produce more heat. So if you have a single radio wave and move toward it quickly, it would be encountered as infrared, and it would be hotter due to the blueshift, but if you move toward that same radio wave even more quickly it would become red light and would be cooler than when you moved toward it less quickly; the same blueshift effect results in a temperature change in different directions, as you increase on the magnitude of the effect (the speed of approach). So the actual heat experienced would increase and then decrease as a function of speed moving toward the source of the radio wave. 

This concept is bizarre to me; does this uneven heat shifting represent a phase break that feels somewhat obscured? This feels like a mystery similar to how most matter reduces in volume when solidified, but water actually increases in volume when turning to ice, although I feel this light shift effect has not, as of yet, been as closely examined. In the same way that Sir William Herschel discovered infrared light by accident through its high heat and a prism, could this uneven shift effect be another clue meant to be found, illuminating something presently unknown (at least by me) regarding the nature of EM waves? Why would such a phase break exist just outside of our field of vision, if it does not exist in the same way elsewhere in the spectrum? It feels like this was meant to be found/discovered, so that reality is revealed step by step for mankind, and reminds me of the narrative of the discovery of "green" in my post regarding the "100 wise men with hats." I am guessing the difference here has something to do with the specific resonance of light with matter at varying frequencies, like the radio waves pass through without much interaction whereas infrared is like the shoreline where waves crash, which is to say the EM wave suddenly resonates with matter and instead of passing through and not transferring as much heat it now collides and does transfer much more heat. Then the rest of the spectrum, to a point, crashes in much the same way but with less intensity. Still the question for me remains- why here, at this point in the spectrum, just outside of our ability to see? Is there something currently unknown in terms of the nature of EM waves, the nature of matter, perhaps even the shape of the fundamental laws of reality in terms of resonance as heat, that is as of yet undiscovered? It is possible these things are known, but I have been an amateur physics enthusiast since highschool (perhaps before), and I have not heard of anyone illuminating this point.

This is an interesting thought to ponder anyway, stemming from the idea of seeing the invisible, as I dive into my long Saturday.

Added Note: If you set up an apparatus that rapidly oscillates toward and away from a source of infrared energy, it could interact with the EM wave as red light (or orange, yellow, etc.) when moving toward the source, and radio waves when moving away from the source. In each case the heat would be reduced from what it would have been as infrared light, so the area behind the apparatus would receive significantly less heat than it would have without the apparatus. If the power source for this heat shield were in an area where the added heat was not an issue (outside a zone versus the shielded area being inside a zone) then this would be a legitimate way to block heat in an area. It is unclear to me though if generating this degree of oscillating velocity in an object of sufficient size is within our current technological capabilities or not.
