CHF 11S Power steering fluid... Clear or green?

[martialmedia]

I just purchased a 2003 Boxster S. I was just checking the power steering fluid level and it was low. It wasn't showing on the stick. I dipped in further with plastic rod to see how low and noticed that the fluid on the stick was clear when I wiped it on a paper towel. I thought that the CHF 11S fluid was green. Is that the case? if so, I hope that the previous owner didn't fill it with another fluid. I guess tomorrow, I'll open the front engine access and see if there are leaks from the pump. From what I understand other fluids eat the seals. Any comments or input would be appreciated.
