Also I want to change bgcolor and background to suit my site.
How can I make the developements?
If you mean within the Ringink program, you just edit the info in gentools.pm
here:
@::ringcolornames = ('colbg', 'coltablebg', 'coltxt', 'colemph', 'colerr',
'collink', 'colvlink');
@::defaultcolors = ('#000033', '#000099', '#ffffff', '#ffff00', '#ff0000',
'#00ff00', '#ff8000');
You may also wish to edit the admhtml.pm, and mainhtml.pm
For a more detailed explanation see the Ringlink FAQ Page:
