Style options OSP Trans. template does not appear

The choice of style OS PROPERTY TRANSPARENT TEMPLATE does not appear in backend as indicated on the site.
I wanted to choose a color style for my site but the options of choosing the style does not appear in my temple while it is said on this page that there are 5 choices of style. Help me understand please. Because I change the style of black color but I do not find the color lines change with firebug and webdeveloper. thank you

Hi Benjamin,
I think there is the misunderstand here, because OS Property transparent template only has transparent black layout. And you can install the module to setup the background pictures.

Ok, please thus correct the description of the template on your website.
Can you thus tell me the file which manages the general black color of the template in order to correct it myself to have a white color.
I have to try to find the lines to modify template.css with firebug without sucès.
I wanted used another template as VERTEX 2 but when the Slideshow module is activated, I obtain an empty white page. The problem is useful posed already at least with two templates different. Thank you
Excuse my English, it is a translation of google.
