Holy Trainer - Clear vs Dark Color?

I own the transparent Holy Trainer, but I find myself increasingly drawn to photos of men wearing the black version. I actually went ahead and placed an order for one already; now I just want to know what everyone else thinks.

To me, the black model makes my penis look completely hidden and therefore less significant, which strikes a particular fancy with me.

I’d love to hear your thoughts on this. Feel free to leave comments along with your preference if you wish.
