  • I have 2 lines of though to explain this, both going totally different ways.

    I am not a chemist, and polymeric science is arguably my worst. so take everything with lots of salt

    I do not know your sex (yes), but for the first one it maybe matters.

    Humans basiccaly have best perception of greens. we have 3 kinds of cones (color detecting cells) and it is basically blue and green and a little redder green (it effectively works as red detector), and we percieve much better granularity in green color spectrum. also those who are female at birth are better at this (some source that i remeber said something in line of 10x more colors observable by females than males). so it is possible all kinds of dyes degrade, and wwith greens you are better able to percieve it. this is in theory testable by perfectly caliberated camera and lighting and displays, and measuring the pl response (doable in a lab setup).

    more likely reason is dyes degrade. dyes are often organic (organic in sense of carbon containing) aromatic or more generally resonant structures designed to have absorption in specific ranges. the wavelengths they absorb the most, or reflect or transmit (as in allow it to pass) determines their colors. for example, our sun has peak emmision around green wavelengths, and life on earth evolved too roughly reject that (they absorb lower and higher wavelengths, if they absorb the most common, they probably die faster). if i remember correctly, organic dyes in paint often absorb the wavelength and then emit (resonance, the color being the resonant frequency) the light, so green dyes get the most common light (assuming the paint is applied on a surface recieving sunlight, if not, with leds for example, it is a bit bluer), and hence has a higher degradation rate. dyes degrade by general oxidation or any other chemical reaction, and that could also be possibly more likely on certain pigments as compared to others, and thegreen one just might be more reactive one. If pigment is inorganic, then it is whole different can of worms - whatstarting compound - lets say FeO (II), which may oxidise further (green -> brown) or something else.

    Without much to go by, there are just so many possibilities.

    basically any amount of energy conversion is lossy - a loose fabric stretching and pulling on frame in a “wider fashion”, and any deformation of frame will require a lot energy - all subracting from your fall. and fame up in your tushie is at worst a life long pain in sitting or in bowel moments, a direct fall is iinsta death from basically anything above, lets say, 10th floor (pulled number out of thin air, but assuming a roughly flat contact, and human not falling like a diver reducing the direct load o spine(by crushing their arms))





  • they are federated just as piefed is, but the difference is that in lemmy/piefed, you do not want to follow particular users, you follow communities. on peertube, you follow users. so when you watch a video on one instance, you can watch a video from different instance too, its just that peertube does not have a great recommendation algorithm. in lemmy/piefed, when you go to home page, and just search something, content from all comunities is shown. in earlier versions of peertube, you could not search across instances. now you can. if you want a better search, try - https://sepiasearch.org/
