Style
Styling GeoServer is a topic in and of itself. We use an open standard called Styled Layer Descriptor (SLD), an open standard XML based language to describe how maps should look. We recommend you start at SLD Intro Tutorial for basic information on Styling and SLD's, plus how you go about loading one in to GeoServer.
Since GeoServer 1.3, GeoServer has used a SLD-WMS, meaning clients can specify the SLD files to render the layers with. Additionally GeoServer uses SLD files internally, to define the named (persistant) styles. To specify a new style you must first create an SLD file. For more information about creating an SLD file, see OGC SLD Explanations and Samples. Once you have defined an SLD file you can upload it to GeoServer.
