Just because I'm feeling like an enabler right now: When the beads are saturated they are clear, when they are dry they are white. You want to try and keep them so that they are mostly clear, with a few stray dry ones in case of flood or other acts of God. Unless you live in a tropical rain forest where the humidity is always above what we're shooting for with our cigars, then you want the opposite, mostly white beads so they can suck up the excess moisture from the air.
ps - all this info in on the website for where you probably bought your beads from.
