The example features some \definecolor's which I just did away with (sadly) by simply substituting their defining values for their occurences. (This is unfortunate, but perhaps necessary until some other mechanism is produced.) The problem is that the text box to the right of the picture is supposed to be colored, and with rounded corners. But the box is missing. Look at p. 20 of

The TikZ manual make a lot of uses of the xcolor syntax (e.g. \color{red!20}). There is no equivalent ConTeXt syntax. You need to define a color, say lightred, as follows

\definecolor[lightred][r=0.2]

For tikz key-value options, pgf works behind the scene to define appropriate colors, so xcolor syntax works for them. So \fill[fillcolor=red!20] will work as expected. However, when using \color inside any box, you need to follow ConTeXt syntax. So \color[red!20] will not work, you need to define a context color and then use that.

I'm still not able to get fillcolor to work with the information box:

\starttikzpicture[scale=4,information text/.style={fill=red}] \draw[xshift=1.85cm] node[right,text width=6cm,information text] { The \color[green]{angle $\alpha$} is $30^\circ$ in the example ($\pi/6$ in radians). The \color[red]{sine of $\alpha$}, which is the height of the red line, is \startformula \color[red]{\sin \alpha} = 1/2. \stopformula By the Theorem of Pythagoras ... };

Is ConTeXt correctly parsing the key "information tex/.style"?

Works fine here. The text/.style syntax is new in Tikz. Are you using the cvs version of tikz?

No, I'm using the module from the garden, corresponding to the 1.18 release. I just installed the CVS version, and, after recompiling, I see that the backgrounds are still missing. One possible explanation: I'm using the old TPM file that's on the modules page. That should be updated to reflect the file structure of the new CVS version, right?

I spoke too soon -- it looks like things work just fine. Thanks for your help! Jesse -- Jesse Alama (alama@stanford.edu)
