Spectra of the atmosphere models with different metallicities and the standard mass loss rates. At lower metallicities the line strengths decrease until they even go into absorption. In the bottom panel we zoom in on a few regions with strong lines. One of the strongest lines is the HeII λ4686 line which also goes into absorption when
