At the beginning of 2021, a customer visited Senfung and brought a cellphone case with anodizing blue color. They wanted a similar blue color on the lens frames with PVD coating. As we all know, anodizing coating is with high gloss and high L value which is over 70. 

Even through the color matching was very difficult, Senfung R&D team had hold project kick-off meeting immediately. After over 20 batches PVD trials, eventually they have accomplished the light blue color PVD with fancy light effect.
