Hi Zaphod > I stumbled upon tw5gray <http://tw5gray.tiddlyspot.com/>, a 2-3 -year-old TW > (5.0.5 beta) the other day
5.0.5 is very old by TiddlyWiki standards. There have been a lot of additions and modifications to the core since then. In particular, the “colours” tiddler you encountered appears to offer the same functionality as the now built in palette mechanism. Under the Control Panel Appearance tab you’ll find a palette tab which allows the current palette to be switched and edited. > This is for a movie database of sorts that I'm working on.

There’s nowhere else in the core or elsewhere that we have a similar technique of making a global style change in response to a particular tiddler being opened. The approach I would suggest would be to use the current tiddler field of the $:/HistoryList tiddler to transclude an image tiddler. You’d have to arrange the titles of the image tiddlers to be related to the titles of the tiddlers you’re viewing (eg adding `-image` on the end). > Also have a drop-down list available (perhaps in the SideBar) with links to > external graphics (the pre-selected screenshots from all/most of the movies, > listed as the movie's title) that the user can choose from and it will > immediately become the background image of the page. That’s a good deal easier - you can see something very similar in the Theme Tweaks tab of Control Panel. You can copy the code from there and just modify the filter of images to limit it to your screenshot tiddlers.
