Here are the traditional belt ranks in Jujitsu training:
Jukyu (white belt)
Rokyu (2nd degree blue belt)
Gokyu (1st degree blue belt)
Yonkyu (green belt)
Sankyu (3rd degree brown belt)
Nikyu (2nd degree brown belt)
Ikkyu (1st degree brown belt)

All though the traditional belt ranking system is quite common in Jujitsu, it varies from club to club!
