Color code WMS maps

Question

I have various WMS map layers showing state/province capitals and various lower level administration (e.g. district) headquarters.

I want to demarcate the state capitals and district headquarters using colors or something else. By default both are in red.

I am using GeoServer with OpenLayers.

Is this even possible, since I have done some searches, but it results only in stylization of vector layers; not WMS layers.

Answer 1

You should use stylization on server side. I hope this tutorial will be hepful.
