Heat map showing the probabilistic distribution of the absolute color (M_V, max − M_I, max) and magnitude (M_V, max) at the maximum brightness (i.e., the sum of intrinsic luminosities of both components) of CBs for the LMC and SMC. The OGLE data are marked as follows: OGLE bona fide CB sample (blue diamonds), OGLE EW+ subsample (yellow circles) and OGLE Rest (grey dots), which is the sample with morph parameter c > 0.7 and P ≤ 3 days that did not make the cut into either the EW+ nor the bona fide CB sample. For reference, the theoretical ZAMS and TAMS curves from Fig. 1 are also marked.
