Evolution throughout the HR diagram for several other events: The SN impostors SN 2008S, SN 2000ch and SNhunt248 and the type IIn SNe 1998S and 2010jl. Colored boxes correspond to the three main epochs of SN 2015bh as in Fig. 15. SN 2000ch occupies a very similar region to SN 2009ip and SN 2015bh in the LBV phase and could be a similar star in this pre-main event period. SN 2008S was always redder than SN 2009ip and SN 2015bh at much lower luminosities. SN 2010jl and SN 1998S reached higher magnitudes than the main events for SN 2009ip and SN 2015bh. SNhunt248 occupies a similar region during the outburst phase but has a lower luminosity at peak. The small late blue turn corresponds to a bump in the LC past maximum.
