Hm. It turns out that your math coloring fix doesn't work perfect: Amsmath implements an equation* environment, which works in exactly the same manner as the displaymath environment (I suspect it actually is an alias) in creating an un'numbered equation. The peculiar thing is, displaymath gets colored, but equation* doesn't. (Naturally, it is not a very big deal, since I can use displaymath instead.) Henrik

*sigh*
I have to admit the colormath code is among the most
fragile parts of TeXPower.
It tries to be as minimal invasive as possible, but
in fact it seems impossible to do this kind of thing
without meddling with a lot of internals, of LaTeX
and of other package intruding into the same areas.
Of course, among other problems, this leads to the
unfortunate situation where any change in any external
package can break the whole thing down.
In this case, it seems the handling of the equation
environment by amsmath has changed in version 2.x.
Before, it was redefined to be a variant of gather,
so it was handeled by the \everymath hack.
Now, it is treated as a normal displayed math
environment.
I've made a micro-update of texpower 0.08f which
now checks for amsmath 2.x. This is also updated
in the development version of texpower 0.0.9b at
http://lrb.cs.uni-dortmund.de/~lehmke/TeXPower/preview/texpower.sty

Your code below works fine for me:
pdfTeX Version 3.14159-1.00a-pretest-20010806 (Web2C 7.3.3.1)
under
Digital Unix, OSF1 (V4.0 1091 alpha).
and as Wendy says, it doesn't matter which order is used
to load the packages.
The texpower.sty package file shows these versions:
\def\fileversion{0.0.8f}
\def\filedate{2000/06/27}
and my tpoptions.cfg and tpsettings.cfg are both empty.
My color.cfg is the standard one from a TeXLive CD:
\@ifundefined{pdfoutput}{\ExecuteOptions{dvips}}{\ExecuteOptions{pdftex}}
\endinput

There must be something else wrong too.
Check your .log file for a simple job, to track which files
are being loaded. Perhaps you are getting something for dvips
rather than for pdftex ? (Though that should lead to trouble
with all math environments, not just one.)
Maybe you are loading a non-standard version of something,
which has coding that isn't as clean as it could be.
Without seeing a .log file, there's nothing more I can suggest.
Hope this helps,

Interesting. I think (hope!) that it has to do with different versions of amsmath, rather than with different operating systems.

Re: Math coloring
Henrik On a Mac OS 9.1 using Textures 2.1 Your minimal example works no matter where the amsmath package is included, if you intended the text to be blue, and the math to be green. However, in the first and longer example, all the displayed math is in green except for this one $$ a = b + c $$ %

Sadly, this doesn't do the trick -- as the (now minimal)
example reveals. But the example is also capable of showing
that it is amsmath's «fault».
But thanks, I apparently need to be reminded that it is wise
to load texpower very, very late.

Here is some displayed math

Math coloring
In many cases, the math coloring works nicely. However, with
one of my most common ways of displaying equations, it does
not work! I have included an example -- it isn't strictly
«minimal», but it shows several types of math, some of which
get colored, some don't. I haven't been able to find a
pattern of which equations do and which don't.
Henrik.
