With my experience with silica Gel beads is that they are white in color and have indicator beads peppered in. The indicator beads are blue in color and turn pink when they have absorbed their limit. Then the batch needs cooking again.
You should be able to get some blue color beads off ebay rather cheap to mix in with yours. As with no color change you would not have the indicators telling you the condition.
