Literally, blood moon would read "lune de sang" in French. Many people would think you refer to its colour throught the atmosphere.
If the question refers to the book "four blood moons" published in 2013, the blue moon refers to a succession of four lunar eclipses, that pattern being touted as heralding the end of times (although there is nothing unusual in it). There is no translation for that, and no translation for the book either.
