Dear Pedro,
which version of GeoServer are using?

Starting with GeoServer 2.12, support for "mixed color model" granules have
been improved:
http://docs.geoserver.org/stable/en/user/data/raster/imagemosaic/configuration.html#granules

You need to have JAI-EXT enabled.
The above link contains more info on that.

Hope this helps.
Cheers,
Daniele
