I've some questions about alpha color in rrdtool produced:

root:~# rrdtool -v

We've attached pcol-day.png for more clearly, here snapshoot my code:

AREA:PCOL#00519933:"" \

#519933 is "green" color. But #00519933 is "blue" in my view. AFAIK, in 
XML Android #00519933 should be "green light" in my view. Another case, 
#8C1DA2 is "purple", but #008C1DA2 produced "green". How to determine 
alpha color in rrdtool?

Thank you.
