Abstract Accreting WDs are very important for the studies of binary evolution, binary population synthesis and accretion physics. So far, there are a lot of accreting WD binaries with low accretion rates, such as cataclysmic variables, detected by different surveys. However, few accreting WD binaries with high accretion rates have been detected. In this paper, we studied the spectrum properties of accreting WD binaries and investigated whether accreting WD binaries with high accretion rates can be detected by the Chinese Space Station Telescope (CSST). We found that some accreting WD binaries with high accretion rates can be distinguishable from other types of stars with (NUV − y, u − y), (NUV − r, u − g), (NUV − i, u − g), (NUV − z, u − g) and (NUV − y, u − g) color–color diagrams. Therefore, some accreting WD binaries with high accretion rates can be detected by the CSST
