Though not a particularly successful racehorse, he has left a legacy in the stud, particularly in passing on the grey color found in most Thoroughbreds in modern times, due to his offspring The Tetrarch, Royal Canopy, and La Grisette.

Notable progeny include:[2][3][4][5] The most common source of grey color Thoroughbred horses is through Roi Herode.

[3][7] This influence can be found primarily through his son The Tetrarch and daughter La Grisette (4th dam of Native Dancer).

[2] The Tetrarch grey color influence has been most pronounced in modern times due to the stallions Tapit and Unbridled's Song.

[8][9] Bonne Nuit, who was grand sire of Roi Herode through his son Royal Canopy, started a dynasty of show jumping horses in the United States, which helps perpetuate the grey color influence through show jumping horses.
