How change theme according to customer group id ?

[Greyg]

Hi,

 

I have 3 customer group in my shop (without guest etc..).

 

I would like to had a specific theme (just color switch) for customer group.

 

Exemple :

 

A customer from group 3 is connected, the template is green.

A customer from group 4 is connected, the template is purple ...

 

It is possible ?

 

And how can i do the same idea for the homefeatured product list depending to customer group connected ?

 

Thanks

Override the FrontController's SetMedia.

 

Have it check the customer group and return a css accordingly, instead of 

$this->addCSS(_THEME_CSS_DIR_.'global.css', 'all');
