What color codes are associated with lanthanated tungsten?

Explanation:
Lanthanated tungsten electrodes are identified by blue or gold coloring. That color coding is used to signal the presence of lanthanum oxide in the electrode, helping welders quickly distinguish it from other tungsten types. Lanthanated tungsten offers stable arc start and good life across a range of materials, and it works well for both AC and DC GTAW, which is why this color set is closely associated with it. The other color groupings correspond to different dopants (for example, red or yellow are used for thoriated or ceria/ceriated electrodes, green for pure tungsten, etc.), so blue or gold uniquely identifies lanthanated tungsten.
