No, it bounces back at the frequency it already is before it hits anything. The act of bouncing doesn't change the frequency / wavelength.

There are similar problems in the remainder of your argumentation. It's a house of cards, with the exception that yours doesn't actually stand.

No. You're just throwing random words together, making up your own meaning to them (which will turn out to be internally inconsistent) and then calling it an 'understanding'.

You could publish it as poetry or some kind of stream of consciousness. You could use it as a sort of mental amulet to get you through the day. But with science, it has fuck all to do. Sorry.

Alright then, since you understand it so well, please explain a couple of things to me.

Quote:

the color gets absorbed by the pigment.



Define 'the color'. What is it, according to you?

Quote:

The reflection is the wave without the color it reflected from.



Define 'the wave'. It sounds like you're talking about it in the singular. Explain how a single wave would have 'a color' substracted from it.

Quote:

You then detect this as color. Yup, look it up. It’s the reverse wave form of the pigment you reflect the light on.



Explain how the wave form relates to color. Explain how inverting this supposed waveform would alter color.

You have not answered any of my questions. You say "the actual physics", but you've not touched upon the most elementary physics of color so far.

So again: what is color in terms of wavelength?

And here's another one for you to research: how do we see yellow? And given how that works, what does that mean for your earlier statements about 'yellow' sunlight?

Your story about blue, green and yellow shows you're clutching at straws. It's interesting subject matter, but you'll have to investigate further. Moreover, you'll have to get rid of the apparent feeling of "I've got this" that currently stops you from learning.

I didn't ask because I wanted you to explain it to me. I asked because I hoped that you'd be stimulated to do some very basic reading on the subject. Whether you want to do this, is up to you. Good luck and have fun with physics. Or metaphysics, if you prefer. Don't ever mix them up, again.

Look son, you sound incredibly confused, but the irony is that everyone recognizes it except yourself. I can't blame you for it, nor do I want to give you a hard time. Enjoy your view on physics; if if gives you pleasure giving your personal spin to theory, then so be it.

As to the color thing:

Light behaves as a particle as well as a wave. The color of light is its wavelength, and wavelength is the inverse of frequency. A photon has only one wavelength, and this doesn't change. So if light (photons) with a wavelength of around 550nm (= green) hit a red target, they get absorbed and none reflect. If the target is green, they bounce back. Yes, absorbed photons result in their energy being absorbed by the target as well.

Yellow is a special case because you need to distinguish between pure wavelength yellow (around 575nm or thereabouts) and human-perceived yellow. We perceive single-wavelength 575nm light as yellow, but this is actually pretty rare, and the vast amount of yellow we see is the combination of red and green. The reason for this is that the human eye has no receptors that are specific for yellow. Our brain deduces yellow from the simultaneous stimulus of our red and green receptors. Coincidentally, this is also why we perceive yellow as a bright color, because it creates an effectively bigger (because, combined/superimposed) signal compared to the 'single' colors of blue and green. Note that our blue and green spectral sensitivity is pretty closely spaced on the spectrum; look at the peak sensitivities of our red and green cones and note how little distance there is between them. From this, and the much bigger distance to the retina's blue sensitivity peak you can deduce that our sensitivity to blue/green hues ('cyans') is pretty poor. In an absolute sense, our green sensitivity is pretty big, which is likely due to evolutionary reasons: a lot of our natural environment and plant-based food is green, so it's advantageous that we can differentiate quite well in that part of the spectrum.

Sunlight we can sometimes/often perceive as yellow, but this is a bit of a ruse. It really isn't. The sun effectively behaves as a near-perfect black-body radiator and as such, its emitted wavelengths span the entire spectrum. In terms of visible light, it's white - but how we perceive it, depends on the human eye (see above) and also on atmospheric effect. Note that we see only a tiny bit of the sun's emitted electromagnetic radiation - the vast majority of the emitted energy we don't see because it's either too short-waved (UV and even higher frequencies stretching into xray territory) or too long-waved (> 700nm; i.e. infrared).

The relationship between the perceived color of a star (compensated for atmospheric effects and other effects such as red-shift) is directly related to its temperature, and this in turn relates to its size and stage in its life cycle. In fact, temperature is the main determinant, not so much the 'type of fuel', i.e. its composition. The main energy conversion process in a live star is by definition nuclear fusion, which always involves just the fusion of hydrogen into helium. In bigger stars, the alpha process also occurs, which is responsible for the fusion of helium into the other (heavier) atoms. It's evident that this only happens in the bigger, more massive stars since the fusion of these larger elements requires extreme temperatures and pressures not found in smaller and older (less active) stars.

The composition of a star does indeed contribute to its perceived color; after all, the elements present in a (very hot) black-body radiator will add light emission in accordance with their specific spectral lines - some well-known ones are the orange (and green) line of sodium (known from the old-fashioned LPS street lights, and also easy to demonstrate by holding a sample of sodium chloride in a blue or colorless flame, which will turn yellow) or the various lines of helium. However, the main determinant of a start's color is still its temperature, in accordance with the theory on blackbody radiators (which date back to the 19th and early 20th century, so not particularly 'hot' - but still very solid).

So all the mumbo-jumbo like this:
Quote:

So the neutron is represented as? Green, but wasn’t that blue and yellow? So now what would be yellow and purple? That’s the energy range if you converted light frequency into an energy spectrum.



..is all confused ramblings that make no sense whatsoever. It's incoherent, meaningless and any attempt to make meaning out of it results in falsehoods and further inconsistencies.

If you find this stuff interesting, there are plenty of books to pick up. In the short term, you'll have your hands full on highschool textbooks on physics and the literature used in the first semester of university physics. If you're still hungry for knowledge at that point, and actually understand what you've learned so far, proceed from there. As I said, it's interesting stuff - but I admit that I only dig into it to the extent that I need to understand it in order to do the projects I work on. Which coincidentally revolve a lot around light, color, spectral sensitivities etc.

I'm going to leave you with this to do your own research/studies. Good luck with it all; I hope you find your way in this subject matter, or that you'll at least learn to differentiate between accepted physics and your idiosyncratic construct of arcane metaphysics along the lines of what you've posted so far. It'll help others to more easily figure out what's up if you're clear on what you know and what you make up.

Verbal diarrhea isn't magic, either. It's still shit, though.
