Since the question asks about color arrangements, it means that except the color, the balls are considered as indistinguishable.



Then the formula and the answer are


    number of color arrangements =  =  =  = 25210.



The factorials in the denominator of the basic formula 

    number of color arrangements = {{10!/(3!*5!*2!)}}}

are associated with MULTIPLICITIES of repeating objects.
