**%WIKITOOLNAME%.%WEB% Web Preferences**
The following settings are **_web preferences_** of the %WIKITOOLNAME%.%WEB% web. These preferences overwrite the **_site-level preferences_** in [[TWikiPreferences]], and can be overwritten by **_user preferences_** (your personal topic, i.e. [[PeterThoeny]] in the %WIKITOOLNAME%.Main web)
**_Preferences:_**
- List of topics of the %WIKITOOLNAME%.%WEB% web:
- Set WEBTOPICLIST = %WEB% . \{ [Home](WebHome) | [Welcome](WelcomeGuest) | [Users](TWikiUsers) | [Changes](http://www.dementia.org/twiki//changes/%WEB%) | [Index](http://www.dementia.org/twiki//search/%WEB%/?scope=topic®ex=on&search=.*) | [Search](WebSearch) | Go
\}
- Web specific background color:
- Set WEBBGCOLOR = #FFFFC0
**_Notes:_**
- A preference is defined as: `6 spaces * Set NAME = value` Example:
- Set WEBBGCOLOR = #FFFFC0
- Preferences are used as [[TWikiVariables]] by enclosing the name in percent signs. Example:
- When you write variable `%WEBBGCOLOR%` , it gets expanded to `%WEBBGCOLOR%` .
- The sequential order of the preference settings is significant. Define preferences that use other preferences first, i.e. set `WEBCOPYRIGHT` before `WIKIWEBMASTER` since `%WEBCOPYRIGHT%` uses the `%WIKIWEBMASTER%` variable.
- You can introduce new preferences variables and use them in your topics and templates. There is no need to change the %WIKITOOLNAME% engine (Perl scripts).
