You can set basic colours in Opera pretty easily in the preferences  
dialogues. (OK Gregory, you can't until you ahve a working screen reader  
build, but they are coming)

You can set a user style sheet, too, under Preferences -> Advanced ->  
Content -> Style Options, which is nice. But in most cases you want to  
change a few things, so you need to set one per site:

Preferences -> Advanced -> Content -> Manage Site Preferences. Add the  
site in question, then select the display tab for adding your style sheet  
to only apply to that site, so you can look at how it uses the colours and  
classes and whatever it is that you need to change.

...now to get an interface for easily sharing those setups - or should we  
finish the screen reader work first, or concentrate on ARIA, or fix some  
broken websites with shiny new beta applications, or...

Well, that is a smart way to implement. W3C describes access to those  
colours - and you can use them in browsers now. Developers just need to  
learn that trick.
