No man, I was just joking.
I've experimented with Tren quite a lot over the years and color in my experience comes down to the raw and how it came from the manufacturer/manufacturing process. I've had light colored Tren and left the heat on too long a few times back in the day and I saw no color change at all. It was the same color from beginning to end of the brewing process. I've not seen any decline in potency from testing light and dark colored trens over the years personally.
I now and have for a long time use minimal heat for all compounds. Although some compounds require more heat like Test Base for example.
What I will say about Tren A and E is if the powder sits for a long time even if its vacuum sealed with moisture packs in between seals, it sill goes bad. I brew every bit of Tren raw right when I get it these days to avoid it.
