S-Type Theme [1.0.x]

[Ron-e]

I have error:
WARNING: Footer text has been edited without consent of theme designer!
Please restore the original st-footer div in the master.zmtl file.

So you did removed or edited the footer text and ignored all warning signs of doing this..
Restore the footer, there is an sappared part where you can insert an copyright or something.. 
Check out the custom.css file for more information about branding the S-Type theme like stated in OP.

Updated custom.css to be more clear about this..

Theme variation

Do you want to have your own color variation?
It's easy, just copy the following lines of css to a new css file with a unique name in the CSS directory of S-Type.

Code:

@import url("default.css");

body{
    background-color: #404040;
}

If you want to add your own branding take a look at the custom.css file.

We don't mind if you make a screenshot and let us see your variation..
