It would be highly awesome if making packed dirt from different colored dirt blocks yielded a packed dirt block matching the color of the dirt used. Same goes for sand smelting into glass! Let me tell you something about glass in these games.. I love it. I harvest it like there is no tomorrow. I build things out of it. I can't get enough of it. And the more colors it has, the better! So, I would love if I could take all my pink, green, blue, purple, yellow, and whatever other color of sand and make it into glass of a matching color! Or at least have another way to color glass.
Yeah with most crafted/building materials you can use the paint tool. But for dirt, which is seen in many colors, you can only make brown dirt without some step I'm missing... If anyone knows let me know.
