From left to right, CMDs of (m_F225W, m_F225W−m_F275W), (m_F555W, m_F390W−m_F555W), and (m_F555W, m_F555W−m_F814W). Counterparts showing peculiar CMD position are plotted in blue. Objects that become bluer in the m_F390W−m_F555W CMD might have an accretion disc and/or a WD. Squares indicate those counterparts that were identified also by Kumawat et al. (2024). The step observed along the RGB at m_F555W ∼ 17 in the (m_F555W, m_F555W−m_F814W) CMD is due to issues related to saturation in the F814W filter.
