I work as a laborer for the company ( my job title is bark blower technician/laborer) and yes, most the satellite yards do carry a dark fine bark. If u want a more thicker, dark bark, then yes go with what Jeremy has mentioned. Your best bet would be to go online to Pacifictopsoils.com, search for the yard that's closest to u, and see what they can do for you. Any of the people that you get a hold of will be able to help you, or direct you to someone who can help you with all your bark necessities!!
Depending on location they carry a product called Black Forest Mulch which is essentialy black bark
