Blue gel > "Orange-Gel"

The moisture indicator of the well known blue gel contains a cobalt compound. Since cobalt ist suspected to be carcinogenic also blue gel is placed in an unfavourable light. A discussion if cobalt which is well shielded in the gel is still hazardous has no value since there is a simple heavy metal free alternative available for the same price. So there will be no disadvantage. All what has to be done is to change the habits. The term "orange gel" today is not yet established. Other trade names are: "Silicagel orange" or "Silicagel rubin" (Fluka).
