Nobody has done much real testing on types of heatsink materials and coatings, but i assume the more surface area you have, the more you can dissipate. Color or anodizing wouldn't do much, but having a rough surface would likely provide very slightly an increase in heat dissipation, but unless you're trying to stress test your Pine64 i wouldn't fret over little things like that. Just get some bare aluminum heatsinks, and maybe a fan if you want to keep it cooler.
If I've helped you with something, please leave a rating for my responses.
