I reported about bleeding pistils in thread “Theory about oil color and density” posts #20,25

For sure there are few reasons witch cause different changes of color.
The color bleeding from pistils seems to be pioneering before oxidation & UV.
These trichs were found in a cavern after alco-wash.
They weren’t heated or UV-exposed nor even opened, but they are already colored with red pistils’ color.
I’m sure that UV doesn’t play any role in case of my studies. There is no UV in my kitchen in the evening in winter.
To be more correct - it’s too little UV here to be considered as a reason of color changes.

ICMagger gunnaknow suggested the role of pigments in the coloration of the extract into the red.
-“Red pistills aren't the only culprit for the red colour in oil …
The red colour is probably largely to do with carotenoids and perhaps also anthocyanins.” (click)
I know little about the pigments and their behavior, but I am confident in the significant role of oxidation.
Effect of oxidation on the color change is well illustrated by the dark color of the resin,
ethanol extracted from the filters that were used to obtain resin amber.

Even earlier, in 2008 thread “Resin Tear Drop from clear to red” (click) ,
I registered the change of color of sap from the clear light yellow to dark red during the half-year of storage in a dark place at room temperature.
Those photos are located in the old gallery. I could not shift them here in the form of thumbnails.
I think that's oxidation is the cause of the appearance of dark color in decarboxylate THC,
which should be colorless, as Sam reports about this.
Unfortunately I have not had the opportunity to make these experiments in an inert atmosphere.
Green shatter for me was a miracle for which I have not found an explanation,
I was not surprised by its fragility, but surprised the color, I have not figured out how did chlorophyll got there through non-polar butane.
Jump, I'm not kidding....YOU, my friend, deserve an award!! You are truly scientific, and pioneering. I have utmost respect for you, and your work! You are a real hero of mine, and I have tremendous respect for you.
Not disrespect intended towards anyone else, of course. Especially, Gray Wolf....my other hero. You are both truly scientific pioneers, and I salute you both! Sincerely!
I just sit in awe at the dedication and perserverance and intense knowledge and appreciation of the sacred herb, that some here aspire to.
Thank you all, actually!
But I just want to thank Jump, here, for being my primary inspiration. You have inspired me to go further, and to do better, for myself, and my fellow man.
