To find the different combinations, we need to use the formula for combinations: nCr = n! / r!(n-r)! where n is the total number of items and r is the number of items being chosen. In this case, n=5 and r=3. Plugging these values into the formula, we get 5C3 = 5! / 3!(5-3)! = 10. Therefore, there are 10 different combinations of colors that can be bought.
