List Status Color

Hi everyone 

in the project Iam working on right now 

i have a status for the workflow which tell the user where the order is right now

let say we have an order which after it send it goes to Manger 1 and after his approval it goes to manger 2 and after that finish

so the list will be 

OrderNumber             Date          Status

          1                        3/5/2015      Manger1 Approval

           2                       4/6/2016      Manger2 Approval

           3                        6/6/2016      Finish

i want to change the color for Manger1 Approval to be green
and Manger2 Approval to blue and finish to red

so how can i change the color for the status in a list view as above ?

best regards
