I think it is moisture, somehow. True Terpenes has been really helpful, and I had the same result with 6 different strains, so contamination is pretty unlikely.

increased tocopherols from co2 extraction would give the yellow hint and add some antioxidant properties. if it continues to be something you encounter, that may be something to look into.

Thanks for the tip.

For what its worth ............. from my experience ..... the terps you purchase that have a "fruity" base to them can be susceptible to what you are seeing. I guess what I'm saying is I wouldn't be so sure it's a water issue.

I have never used True Terpenes only Holy Terp. The HT Pure always dissolves into shatter creating a perfectly clear extract. I have been experimenting with collecting cannabis terpenes without solvent using a vacuum oven. My first tests of adding my cannabis terpenes to shatter created a very cloudy extract, but it was fucking strong and the most potent dab that I have ever taken (I used .15ml cannabis terps per gram to test and it was waaaayyyy too strong). I finally dissolved shatter in .3ml HT Pure Flavorless per gram at 120F for 20 mintues, and when fully mixed, I add .05ml of my cannabis terps.

I know that places that sell commercial terpenes are likely using proprietary processes to clarify, filter and purify terpene isolates and blends, but in reality for cannabis is that these are unprocessed. I am not a chemist, but I suspect that are some additional organics remain in terpenes that have not been distilled or dissolved into a solvent.

"The main difference between terpenes and terpenoids is that terpenes are hydrocarbons (meaning the only elements present are carbon and hydrogen); whereas, terpenoids have been denatured by oxidation (drying and curing the flowers) or chemically modified."

So, back the OPs question, maybe True Terpenes accidentally sent you a batch that had not been fully processed?
