Brake fluid?? Likely not, but important.
A quick google search on Subaru coolant color suggests it is teal. (Although some say blue.) However, dealers may not use OEM fluids - I had a Toyota dealer turn my red coolant to purple when they added a green coolant to top it off. (I complained to Toyota, but they told me dealers can do what they want... eventually the dealer drained and filled with OEM.)
Brake fluid should be light amber, per Subaru.com.
Hope it is under warranty?
