Hi,

this is the first time I use tikz and maybe something is missing in my
example. I tried the second graphic from page 206 of the tikz manual.
Sadly I only get a opaque blue square. Example and log file attached.

I get the same error for both marks:

(./tikz206.tuo)
systems         : begin file tikz206 at line 6
Package pgfkeys: Error! I do not know the key '/tikz/innercolor' and I
am going to ignore it. Perhaps you misspelled it.
Package pgfkeys: Error! I do not know the key '/tikz/outercolor' and I
am going to ignore it. Perhaps you misspelled it.
Package tikz: Error! You need to say \usetikzlibrary{patterns}.
Package pgfkeys: Error! I do not know the key '/tikz/patterncolor' and I
