According to a fairly big oil and extractor manufacturer up in the Seattle area, there are many factors that will affect the color of the final product. Some of the big ones are the condition of the buds/material before/during the extraction(fresher material will leave a more translucent finish, older material will leave a darker color), and the temperature of the solvent and material during the extraction process(higher temps = more chlorophyll and a darker finish, but not necessarily bad or burnt). Darker colored buds such as purples will have a darker finished product than light colored buds such as jack herrer. Dewaxing can make the oil into a lighter color and remove some of the remaining plant material but doesn't equate to a "clear".
There are many factors that come into play and color is by no means an immediate way to determine potency or even flavor. I've had some very dark live resin made from a purple that was some of the best oil I've had. Super terpy, full of flavor, very potent and not harsh. It is also possible to have some translucent oil yet have very little flavor or potency.. but typically the "clear" ones are of high grade.
