Where did @wobbly goblin 's post and like go? Odd.
I'm sorry I should have made a shorter version for those too impaired for reading. To me I prefer documented research as opposed to anectodal perceptions; however some research DID show that it can be genetic.
I should have shortened the post to this:
"In many species, anthocyanins are produced only when the plant is unhealthy or has been exposed to environmental stress, but there are some that develop the red pigments even under optimal growth environments."
"Irrespective of their cellular location, however, anthocyanin biosynthesis in many leaves is generally upregulated in response to one or more environmental stressors. These include: strong light, UV-B radiation, temperature extremes, drought, ozone, nitrogen and phosphorus deficiencies, bacterial and fungal infections, wounding, herbivory, herbicides and various pollutants. Because of their association with such biotic and abiotic stressors, anthocyanins are usually considered to be a stress symptom and / or part of a mechanism to mitigate the effects of stress."
if that's not too long there; you can see that an anthocyanic response can happen from both a genetic mutation, or from any number of internal and external factors; which "rarely" can occur naturally. I've found more information, but don't suppose it matters really nor that anyone would care.
I see your picture of "what you believe to be" genetic Anthocyanic coloration and match you with a pic that is for sure related to availability and not genetics. Plant was grown indoors so there was no cold either.
Nope he never saw any coloration except the one. Which he still talked about somewhat excited; though he did comment if had ever found another, he wouldn't have even let it bloom. Again, though here, he was doing Filial crosses each year. If the plant didn't have that characteristic to start, then all of the 400 he did would have been related to how "common" this "genetic mutation" is; as opposed to how common it is relative to different strains. That to me would be a key difference with your situation. I myself have even grown outdoors a couple times in years past and never saw it either; though again was one type and only a couple total numbers.
To me really; the "take away" with what has been posted is that; All colorations are going to be from Anthocyanins. They exist everywhere inside of every plant. In order for any color to occur an "upregulation" and biosynthesis MUST occur to cause coloration to be apparent in these (normally clear) flavonoids. This would be true whether or not it is a normal expression for that particular plant. As well, the mode of action by which coloration results would be the same metabolic process; irrespective of deficiency, stressor or a mutant expression.
Often times i forget some of what I learned from having a fish store. Of all the customers that came in throughout the years; there was only 1 person whom actually wanted to "know why". Most people just want an answer and don't care as to why something happens. Well at the end of the store, only that one lone customer (whom had the initiative and desire to know) actually knew more. Most of the customers couldn't solve their way out of any tank issue. However that one customer knew enough to diagnose but also could even talk about he chemistry related to the issue.
That person was very simple and had a job picking up trash for the city. Probably the least "well off" person that came into our store, knew more than college students. To me it was very fulfilling to see that he learned so much and at the same time so depressing that most humans didn't care.
Sorry to have posted here. As I said before I did not intend to cause problems and information can often do just that. I won't let this happen again, so no worries there.
wow no disrespect but to be honest i didn't bother to read threw all that mostly because I'm way too stoned to put forth the effort and also because this pic is from this summer so no cold weather or etc. to influence just genetics imo at least.

that's a piece of the main stalk towards the top of the plant and a side branch both expressing purple stripes. i just grabbed a branch I'm sure i could find one even more pronounced but it's plain to see.

@MGRox -- I find it fascinating that your friend has only ever experienced one plant purpling due to cold, I see it every year. And again, the color changes (not just purpling, but also features like pink pistils) that only appear where the plant is being hit directly by sunlight.
:)
