Other common colors include yellow to symbolize wealth and glory, gold to wealth, success, and victory, black to power and ward off evil spirits, white to symbolize goal achievement and new beginning, purple to symbolize health or enlightenment, blue to symbolize academic success and promotion, pink to symbolize love, and green to symbolize health and longevity.
Omikuji are paper fortune slips that you can draw at Japanese shrines and temples. There are seven types of fortunes, ranked from best to worst: 大吉 (Dai-kichi, Great blessing), 中吉 (Chū-kichi, Moderate blessing), 小吉 (Shō-kichi, Small blessing), 吉 (Kichi, Good luck), 末吉 (Sue-kichi, Future blessing or good things later), 凶 (Kyō, Bad luck), 大凶 (Dai-kyō, Great misfortune). If they receive a good fortune, they take it home and keep it in their wallet, notebook, or on their household altar. If they receive a bad fortune, they tie it to a designated tree or rack at the temple, leaving the bad fortune there as a way of seeking guidance.
