The main or identifying color of the device.
The main climbing gear certifications are CE and UIAA--and normally the UIAA creates the rules that the CE body also supports. When possible, we try to list all the certifications the product carries.
To sell a climbing product in Europe, the device must be CE certified. There are no official requirements to sell climbing gear in the US. The UIAA certification is a voluntary process.
