I just want to point out that both White Sand and the white powder are based on the vanilla texture, which was created by Mojang. The white sand texture for this mod was created by putting the sand texture in photoshop (or another image editor) and running it through an algorithm to make it white (possibly with a few touch ups afterwards). I'm sure Mojang did a very similar process when making every color of powder (something they also would've done when making the different colors of clay, wool, and glass).
