Your brake fluid was looking a little green
that right there is funny... It dosen't matter what color your brake fluid is as long as its DOT 4 and when you test brake fluid you test it for how much water is in it... I hope u didn't pay for this "color check" and your tranny fluid not begin as red as it should be? They are just trying to get you to get ur service work done with them... You change your fluids regularly you will be fine... I work at a stealership I know the deal the "color check" in my opinion is there game...
