Vanadium is commonly found in 64 natural minerals like vanadinite. It can naturally exhibit in four oxidation states with different colors. When occurring in +5 oxidation state, color will be yellow, appears blue in when oxidation number is +4, appears green and violet in +4 and +3 state respectively. The oxides that occurs in the four multiple oxidation states are VO, V2O3, VO2, and V2O5.
