Dirty/Sandy/Gravelly Snow

By combining powdered snow with Dirt, Sand, or Gravel, this could create Dirty Snow, Sandy Snow, and Gravelly Snow, respectively. They would primarily function as decorative blocks that provide not only texture variation for snow/winter-themed blocks, but also a much needed color variation for snow/winter-themed blocks. 

The 'logic' behind combining them is that the 'loosely packed' aspect of powdered snow provides room to pack in other materials in order to make a more solid block. Thus, the Dirty/Sandy/Gravelly Snow would be a solid block that entities can stand on without falling through.

Thanks for reading and considering this idea!
