Yes, in that pic they do have the colors. They are using a custom texture pack, he has a link there. The issue is, the blocks in MC are still the same, like he uses sponge and mushroom alot. In the texture pack they map to someting nice. This gives them versitility, but for use, it has to match to functionality, not just art. So if I use dirt or something and you spawn it and build it out, you are going to get shot up bad...
We would have to make one, so I am mapping them best I can for default usage. On a side note, there is way too much to use hardened hull. It cost more money than you can have in the game. LOL
I was thinking of posting pics with another texture pack I use later. After it is all maped out. I like the Black myself =] but can test others.
but this is all we have even with another texture pack for blocks http://star-made.org/wiki/item-ids
