>>16984457>anthocyanins are actually blue even though they look violet depending on the pHAnthocyanins actually change their electronic structure and thus their absorption depending on pH (protonation/conjugation.)Your other examples are just inane.
incidentally the color of a solution containing gold nanospheres depends on their size, for an equal quantity of gold
>>16984466yeah I know. what's your point?pH is literally an electronic process.
>>16984557>What's your point?Well, for one, we had no explanation for why colloidal gold is red-blue, why argyria/chrysiasis turns you blue, or why anthocyanins shift colors with the acidity of the soil before the 20th century. (For that matter we didn't know why regular gold was golden)That seems at least vaguely remarkable. Despite not knowing any of this, the Lycurgus cup was produced in the 4th century AD.
>historical Japanese had only one word for blue/green due to Rayleigh scattering>money is green due to gravity because it makes the world go round>gigi d'aggostino is only blue due to depression and would be green if happy but still look blue due to Rayleigh scattering
>>16985019>historical Japanese had only one word for blue/green due to Rayleigh scatteringThe traditional color "ao" referred to a range of dye colors mostly centered around indigo all the way to grayish, which has nothing to do with Rayleigh scattering, and unlike anthocyanins indigo is a chromophore with a very stable conjugation pattern. Neither does the greener color "midori", which referred to the color of foliage due to chloroplasts' absorption.However, the traditional color "aka", now red, was the color of the sky in the sunrise, ranging from pink to orange, which is in fact due to Rayleigh scattering like the sunset sky.Your other examples are just inane.
Rayleigh scattering says blue light scatters more strongly than other colors. Therefore the sky is biue.But violet scatters even more than blue. The eye can see violet. So why isn't the sky violet?
