The spectrum of natural colors and their sources is amazing. Saffron is created from Geru Pathar stone, yellow ochre from Holud Pathar stone, white from Khorimati clay, black from a type of soot called Bhushokali. Orange comes from Kamala Pathar stone, green from Simpata leaves, purple from Pui Metuli leaves, pink from banyan buds or Boter Kuri, red from Phanimansha flowers, blue from Dela Nil clay, and yellow from Palash flowers!
