Soo, a few days ago, i choose Sand Shark out of an birthday color kit, and i really love it. Depending on the material, it has a differend color scheme / pattern. I know, a blue guardian in general is not that innovativ, but bear with it. :D It may look even better on some light armor, but i haven't had the time to try it out yet. For now, only my guardian got a new coating with it.
