Black, Dark Gray, and Green speckles with green numbers. These sets are the Earth Elemental dice. I love elemental dice
Black with Gray speckles and yellow numbers. Of my black speckled dice, this one is the easiest to read the numbers off of.
Space. The final frontier. And a very, very cool set of dice. I picked up 3 sets, thinking I might get in to a space based RPG. Perhaps Alternity. No self respecting space RPG should be played without a set of these. Black dice with white speckles and red numbers.
Black and Gray speckles with Silver numbering. The so called "Ninja set", although I think blue and black would make a better "ninja" color scheme.
Black and Gray speckles with white numbers. This set comes with extra d6's.
