Best looking reef substrate?

[marinelife]

What, in your opinion, is the best looking reef substrate for a reef tank?

I like a mix of sizes and colors. I just added a little Pink fiji coral sand to the top layer. I like the color and size.

i like my sump rdsb, it has 2 20# bags of black 2 20# bags of black/white, and a thing of reef mud on the top. the sand is the real fine stuff.

I prefer fiji pink regular grade. Not too fine and not too large. I also like the way the sand starts to look as it ages. All kinds of interesting shells and rock chips and dead lost coral frags and all the fauna that inhabits the sand.
