I just compared 2 different d-limonene pulls I have sitting here and one is yellow while the other is green...

The limonene that turned out yellow was soaked in the cactus for 24 hours, and the one that turned out green about 2.5 hours like the tek instructs.

Is this color difference only something aesthetic, or is there a real difference and is one better then the other?

Which one was made before? Or where they made on the same material, you had it divided in two halves?

I dont know why the color, but maybe take pics of the limo, salt them out separately, compare the results, take more pics and post here

is it just color difference or is one more opaque than the other?

The yellow one was made before, same matirial but already salted 3 times, the green one has been salted 1 time. But...

I just woke up and looked at the formely green limonene again and now it has rurned yellow also. It's a darker yellow but that's normal I guess bc it's only been salted once so far.

So
