... and just to add to this, there is more information about how to configure
the wmsConfig.xml file here:
http://www.resc.rdg.ac.uk/trac/myocean-tools/wiki/WmsDetailedConfiguration
This describes how colour scale ranges can be defined at the level of a server,
a dataset, a variable or even a standard_name (so you could define a default
colour scale range for all sea_water_potential_temperature variables in all
datasets).
Hope this helps,
Jon

The WMSExtensions link that Marcos provides spills the beans, but sometimes a
quick example helps... note the use of COLORSCALERANGE:
