Hi,
Not a lot of time to look at this in detail, but the following adapts your approach so that the colors can be specified in a roughly similar manner to other shadings, with the addtion that an RGB hex specificaion can be given:
\documentclass{article}
\pagestyle{empty}
\usepackage{pgf}
\begin{document}
\makeatletter
\def\pgfdeclaresampledshading#1#2#3#4#5#6{%...

Hi,
In the latest CVS version (not sure when exactly it came in) there is a 'path picture' key which allows TikZ code and images to be placed within an arbitrary path.
Regards
Mark.

Hi,
you can try (some variation) of this:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\catcode`\@=11
\def\pgfifshapenamed#1{%
\pgfutil@ifundefined{pgf@sh@ns@#1}{\pgfutil@secondoftwo}{\pgfutil@firstoftwo}%
}
\catcode`\@=12
\begin{tikzpicture}[every node/.style=draw]
\node (A) {A};
\pgfifshapenamed{A}{\node (B) at (0,1) {B};}{\node (C) at (0,1) {C};}...

Hi,
TikZ does all sorts of fooling around with coordinates and anything that is passed to the math engine is expanded with \edef which will cause all sorts of problems with \ifthenelse.
The CVS version of math engine contains a new function ifthenelse and new operators ? and : which can be used as follows:
\documentclass{article}
\usepackage{tikz}

Hi,
The following does it (I think) by converting the quadratic bezier to a cubic (this was the easiest way I could think of doing it). You use 'control' (not 'controls') in the curve spec. and TikZ automatically does the rest.
I have absolutely no time to test this thoroughy, so if there is some problem, just post here and I will (eventually) try and improve it.
Regards
Mark...

Hi again,
A much shorter solution is to fill all the colours in at once, this means there is no fooling around with the even odd rule:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\def\fillvenn#1#2#3#4#5#6#7{%
\fill[#1]\truth;
\fill[#2]\thA;
\fill[#3]\thB;
\begin{scope}
\clip \truth;
\fill[#4]\thA;
\end{scope}
\begin{scope}
\clip \truth;...

Hi,
It's a bit crude, but the following gives a rought idea of one way to approach the problem:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\def\AnBnT#1[#2]{
\begin{scope}
\clip \thA;
\clip \thB;
\fill [#2] \truth;
\end{scope}
}
\def\AnB#1[#2]{
\begin{scope}
\clip \thA;
\fill [#2] \thB;
\end{scope}
}
\def\AnT#1[#2]{
\begin{scope}
\clip \thA;...
