+This is the README for colourchange.sty.
+
+Changes colour of beamer structural elements (e.g. the bars of outerthemes).
+This is done either manually or automatically.
+
+Don't use a colour theme or full theme (which sometimes call colour themes).
+You should be OK calling inner themes and outer themes separately (although some look better than others at the moment: see bottom of readme).
+You need to compile twice for it to work.
+
+Requires packages etoolbox and calc.
+Also needs some other stuff that is loaded by beamer.
+Use with other classes at your own risk.
+
+%------------------------------
+% Summary of commands
+%------------------------------
+
+\selectcolourchanges{first}{second} takes two arguments: the starting colour and the final colour of the presentation.
+These should be colours already understood by beamer.
+Beamer uses xcolor, so you can define colours with xcolor commands and then use them in \selectcolourchanges.
+That's what I do for the defaults.
+
+\selectmanualcolour{colour}
+Changes the structure colour.
+Use between frames.
+Can't guarantee this won't do weird stuff if you also have slidechange or framechange on.
+
+Both commands also come with an american spelling version.
+\selectcolorchanges and \selectmanualcolor are defined to be the same as the above two commands.
+%------------------------------
+% Summary of options
+%------------------------------
+
+defaultstyle
+Turns on default inner and outerthemes.
+Or rather, it will do soon.
+That is, it turns on my favourite version of the theme, not the "beamer default" ones.
+This is just a shortcut for:
+\useoutertheme[footline=authorinstitutetitle]{miniframes}
+\useinnertheme{rectangles}
+Simple.
+
+draft
+The draft option turns off colour changing.
+Good for speeding up compilation when drafting.
+
+slidechange
+Colour changes every slide.
+
+framechange
+Colour changes every frame.
+
+%------------------------------
+% To do list
+%------------------------------
+
+Make sure it works with all base inner/outer themes.
+ - smoothbars, smoothtree do some shading-fu that breaks colourchange.sty's basic approach.
+Check it doesn't hopelessly break article or handout modes
+Make a .dtx

+\section{Introduction}
+
+The \lstinline+colourchange+ package provides options for changing the colour of beamer's structural elements.
+There are two ways to do this: manual and automatic.
+
+\section{Manual}
+
+The command \lstinline+\selectmanualcolour+ sets the colour to its argument.
+It accepts any named colour understood by \lstinline+xcolor+.
+
+\section{Automatic}
+
+There are two options that automatically change the colour: \lstinline+slidechange+ and \lstinline+framechange+.
+Pass one of these to the package as an option and the colour of the structure will slowly change from one colour to another.
+To set what colours the transition should be between, use: \lstinline+\selectcolourchange{first}{second}+ which makes the colour transition from
+ \lstinline+first+ to \lstinline+second+ over the course of the presentation.
+
+You will need to compile twice to see the effect since \lstinline+colourchange+ needs to know how many slides there are so it knows how far
+ through the presentation it is at a given point.
+
+\section{Usage}
+I have been testing this by calling it as a standard package, I'm not sure how \lstinline+\usecolortheme+ deals with package options.
+So if you want to use the manual colour changing option, all you need is: \lstinline+\usepackage{colourchange}+.
+If you want one of the automatic colourchange options call \lstinline+\usepackage[slidechange]{colourchange}+ or
+ \lstinline+\usepackage[framechange]{colourchange}+.
+
+You can pass the option \lstinline+defaultstyle+ to the package, this sets up the structural elements (the inner and outer theme) so that they use the colours.
+Otherwise, you can use Beamer's own \lstinline+\useinnnertheme+ and \lstinline+\useoutertheme+ to use the themes Beamer defines.
+Call inner and outer themes separately.
+Some ``all inclusive'' themes call a colour theme themselves and this can lead to only some elements changing colour.
+
+Use the \lstinline+draft+ option to turn off the colour transitions.
+
+\section{Known problems}
+
+The \lstinline+smoothbars+ and \lstinline+smoothtrees+ outer themes do some funky stuff with shading and colours, so they aren't currently supported.
+All other outer and inner themes looked alright.
+Testing was, however, pretty basic: not all combinations were tested.
+
+\section{How it works}
+
+It's a pretty simple package really.
+Just like (some) basic beamer colour themes it defines all the components of the inner and outer themes
+ in terms of one ``master colour'' called \lstinline+structure+.
+Then all it does is use various ways of changing this colour.
+The manual option just gives you a way of changing this colour on the fly.
+The two automatic ways basically fiddle with beamer slide and frame creation internals to set the structure colour whenever a new frame/slide is created.
+See the \lstinline+.sty+ file for details.
