I turned on the logging mode, the output related to the background color was:

The background color outside of the raster object should contain nodata values only (which is set to -9999 in this case). Debug session or jar-file with additional output would be great! -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Geoserver-ImageMosaicJDBC-returns-grey-color-for-out-of-bbox-region-tp5255345p5256364.html Sent from the GeoServer - User mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Transform Data into Opportunity.
