Small correction for the text in the page: Although the character for "Hatsu" does mean prosperity, Hatsu represents sincerity according to the myth. Going along with the source I found before the correction though, I used prosperity to characterize her.
According to myth (as before):
白 (Haku)- the white dragon, representing filial piety
発 (Hatsu)- the green dragon, representing sincerity (character means prosperity)
中 (Chun)- the red dragon, representing benevolence
