its either cleavage, color or fracture

No. It can vary from the visible color of the mineral and, since visible color of them ineral is not a reliable indicator of type, it is important to learn to use streak, (along with other factors), to correctly identify a mineral.
Color, due to the effects of impurities, is the least reliable identifying mineral characteristic.
A sapphire gem is mainly composed of the mineral corundum and other trace mineral impurities that give it its color.
Sapphires are composed of the mineral corundum and impurities that gave it its color.
Rubies are made of corundum (aluminum oxide, Al2O3) with trace impurities that give them their color.
Besides air and water, there are several things that can change the color of a mineral. Impurities, age, the sun, heat, and pressure can change the color of a mineral.
