Ploesti Raid desert pink was Sand No. 26. The best modern equivalent is anything that comes close to FS 31433. The source states that "for color, the closest option would be flesh-colored equivalents, not too pink and not too light."
Assuming you are looking for USAAC Sand No. 26, here are some good options:
Lifecolor UA 709
Tamiya XF-15
Vallejo 70.804
Xtracolor X406
