I'm using the following to generate a Venn diagram, per the example here:
\documentclass{book}\usepackage{pgfplots,tikz}\usetikzlibrary{patterns}\begin{document}\begin{center} \begin{tikzpicture} \begin{scope}[blend group=soft light] \fill[blue!30!white] (135:1.2) circle (2); \fill[red!30!white] ( 45:1.2) circle (2); \fill[gray!30!white] (-90:1.2) circle (2); \end{scope} \node at (135:2) {1}; \node at ( 45:2) {2}; \node at (-90:2) {3}; \node {6}; \end{tikzpicture}\end{center}\end{document}However, instead of blue, red and gray I would like to use pattern fills like crosshatch or dots, per the tikzpgf manual, page 217. When I try swapping the name of the color in the fill with the name of the pattern, the diagram no longer compiles. What gives?
