I am adding features by using var feature = new OpenLayers.Feature.Vector( new OpenLayers.Geometry.Point( lng ,lat ).transform(epsg4326, projectTo), {description:'some description'} , {externalGraphic: 'mypicture.png', graphicHeight: 32, graphicWidth: 32, graphicXOffset:-16, graphicYOffset:-16} ); But they are barely visible given that almost all colors are being used in osms. What is a good practice to make icons visible on osms?
