1. How do I change the primary colors of my theme? like from purple to dark red...

2. How do I go about adding a full banner to the header of the page? (I want it to take up all the space)

3. How do I change things about the registration form... like how do I change the word avatar to picture?

In these forums "please answer " is not needed..

Your theme colours are set mainly in the style.css and perhaps the theme.html file in the root of your theme folder. Have an explore in these, look for colours set in the "body" tags and tables etc. In the style.css right and left blocks for example have colours specified. Specifics depends on the theme you are using, but they all work on a similar principle.

2. Assuming your theme has the banner code included in the header in theme.html, you will probably need to take out other cell tags to allow space i.e.

<{$xoops_banner}>

but you would need to tweak this to get it to fit height and width etc, the example above has one row, and one cell.

3. modules/system/language/english/admin/users.php

this has some avatar definitions, these words are defined in the language folders for each module, but this one is a system definition.

This is just a general answer if you have more specifics just post again
