SparkFun Thing Plus

I purchased a thing plus some time back and just got around to using it, it has been in the sealed bag that it was shipped in.
I noticed that the solder pads are black, will they accept solder or is the board defective?

Hi, has anyone contacted you yet regarding this issue? If not, I think it’s better to mail robotshop team with your invoice number and a close photo of the solder pads.
