Comparison of all targets in the LMC (black) and SMC (gray) in multiple CMDs of M_G versus BP − RP (upper left), M_V versus B − V (upper right), M_KS versus J − K_S (middle left), M_IRAC2 versus IRAC1 − IRAC2 (middle right), M_IRAC4 versus J – IRAC4 (bottom left), and M_MIPS24 versus K_S – MIPS24 (bottom right). Massive star candidates are color coded in blue (BSGs), yellow (YSGs), and red (RSGs), with dark and light colors indicating targets from the LMC and SMC, respectively. There is a prominent difference at the bright red end (RSG population) of the optical and NIR CMDs; this is illustrated by LMC targets which are shown in a redder color than the SMC ones. Meanwhile, this trend is reversed in the M_IRAC2 versus IRAC1 – IRAC2 diagram with the LMC targets in a bluer color.
