What to use to seal gaps between slate veneer on vertical exterior walls of home

Question

I have slate veneer on the exterior walls of some parts of my home.  There are gaps between the various uneven pieces of slate which protrude off the wall to different levels (i.e. each slate piece has a different thickness).  What colored (the slate is black in color) tube caulk product would you recommend to seal these gaps?

I would use 100% silicone from GE or DAP. Unfortunately, pure silicone has less color choices. Black might be blacker than your slate and look odd. Dark gray might look best, but I don't know if you can find it.
