I agree with this. I typically look at Top sellers, but that isnt always the best way to measure. Popular producers sell a lot of the top clips, but I've found some that were pretty good, despite not being in the top 10 slots.
I like dark green or medium blue. back about 15 years ago, brown was popular among light skinned ladies in the upscale area where I was working atthe time. It may not sound like it, but it wasnt a bad look either
