(u − r)₀ versus (g − i)₀ (top panels) and (J0378 − J0515)₀ versus (J0660 − r)₀ (bottom panels) color–color diagrams for white dwarfs with S/N > 3 in J-PLUS photometry (5379 sources). In both panels, the orange and purple lines show the theoretical loci for H-dominated and He-dominated atmospheres, respectively. The black contour enclose 50% of the sources in each panel. The square and the diamond mark the colors for a H- and a He-dominated white dwarf, respectively, with T_eff = 8500 K and log g = 8 dex. The color scale shows the probability of having a H-dominated atmosphere, p_H. Left panels: color–color diagrams for the 4470 sources with p_H ≥ 0.5. Right panels: color–color diagrams for the 909 sources with p_H < 0.5.
