Age of the plant material can change color a lot too. And certain strains just make certain colored oil too. When i ran fresh dried trim it wasnt more than 3 days old just dry enough to run, and it was almost clear. Thinner parts were but in the thick parts they had some yellow.
Cookies always comes out super red. Ive seen a few other strains that are always a certain color but most range from yellow gold to amber orange to darker amber brown to pretty brown. Depending on age and how it was cared for ie. frozen, jarred, cured, etc...
