PURPOSE: A colored mid-sole fabricating apparatus is provided to reduce use of a spray or raw material and to maintain an original color of shoes even if the shoes are worn by installing a colored mid-sole in the shoes. CONSTITUTION: A colored mid-sole fabricating apparatus includes undiluted solution reservoirs(10,12), an undiluted solution passing pipe(20), an impeller member(30), a pigment reservoir(40), and a pigment passing pipe(50). The undiluted solution reservoirs(10,12) receives an undiluted solution used for fabricating polyurethane, which is material of a mid-sole of shoes. Isocyanate is received in one undiluted solution reservoir(10) and polyol is received in the other undiluted solution reservoir(12). The undiluted solution passing pipe(20) has a cylindrical shape, and a diameter of an inlet portion(21) thereof is smaller than a diameter of an outlet portion(24) thereof.
