Hi,

1. The Picture Reloaded theme allows for a LOT of customizing in regard of colors.
http://drupal.org/project/pixture_reloaded
There are others, look around in http://drupal.org/project/themes
The amount of customizing depends on the amount of configuration parameters that are defined and implemented by the themer and the amount of energy he/she wanted to put into the development of the interface. Most of the time a theme is created for a particular use, so customizing is not required.

2. A theme not only defines the colors and images, but also the structure of the site. A theme can override every bit of HTML that is rendered by every module in Drupal. Theming in Drupal is ultra flexible and your pre requisite that the structure of the site should not change is totally contradictory to that.

3. Sub themes override theme structures and functions of the main theme. So you start by a master theme and gradually override parts until you get what you want.
You can not mix two themes like you describe it. A Zen theme can never be a part of a Garland theme. You can start from a Garland theme and copy a part of a Zen theme over.
If you want to venture into this kind of theming, you have a lot of reading and testing to do. It's not basic stuff where you can just copy some files and expect it to work. You need to know more about the inner workings and may not be afraid to get your hand dirty with PHP code.

P.S. If you need theming help, let me know.

Hello

Is there a theme that is configurable and customizable? Let me tell you the background of my question: I want to let users customize their view like gmail does.

My 2nd question is about changing themes. Whenever I change the theme, I lose all the dimensions of the frames and menus. I don't know how themes were developed in drupal, but changing from 1 theme to another should not ideally hurt the look of the site.

And my 3rd question is about sub-theme. I keep seeing this term especially in Zen theme. Does it mean I can run a Garland theme and inside it I can define a Zen theme for a view? OR does it mean I can create a new theme out of the parent theme that is always Zen theme?

thank you for clarifying these 3 points.

best regards,
