Alternate coloring in case of multiple dimensions in pivot table

[ranidas]

Hi Team ,
Need your help in achieving below requirement. 
I have 2 dimentions : Unit and Accounts 
Categories and its respecyive sub categories are populated using inline load in load script.
Each unit Can contain any number of accounts (dynamic).
Each unit needs to be colored same , but accounts present inside each Unit needs to be alternatively colored . 
I am able to achieve  coloring measures by using Dimensionality , but unable to populate color for  unit and account  values section. Coloring should also reflect based on selection of respective unit.
Kindly help.
