Caption: Figure 5.
Luminosity–color tracks for H and He WDs based on models from P. Bergeron et al. (1995), with colors slightly shifted to bring them in agreement with the SDSS photometry. Data, shown as symbols, are the same as in Figure 1 and in the middle panel in Figure 2. Note the crucial role of the u − g color for distinguishing H and He tracks.
