This is not what Mercury would look like to the human eye, but rather by applying mathematical analysis to MESSENGER images, color differences on Mercury's surface can be accentuated beyond those visible to a person. This view uses a global mosaic with  430, 750, and 1000 nm bands and places the second principal component, the first principal component, and the 430/1000 ratio in the red, green, and blue channels respectively.</description><referenceURL>https://alasky.cds.unistra.fr/Planets/CDS_P_Mercury_MDIS-enhanced-color</referenceURL><type>Survey</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsDerivedFrom</relationshipType><relatedResource>https://astrogeology.usgs.gov/search/map/mercury_messenger_mdis_basemap_enhanced_color_global_mosaic_665m</relatedResource></relationship></content><rights rightsURI="https://cds.unistra.fr/aladin-org/licences_aladin.html">This HiPS is distributed under ODbL license by Unistra/CNRS</rights><capability standardID="ivo://ivoa.net/std/hips#hips-1.0"><interface role="std" xsi:type="vs:ParamHTTP"><accessURL use="base">https://alasky.cds.unistra.fr/Planets/CDS_P_Mercury_MDIS-enhanced-color</accessURL><mirrorURL>https://alaskybis.cds.unistra.fr/Planets/CDS_P_Mercury_MDIS-enhanced-color</mirrorURL></interface></capability><coverage><footprint ivo-id="ivo://mocivod">https://alasky.cds.unistra.fr/Planets/CDS_P_Mercury_MDIS-enhanced-color/Moc.fits</footprint></coverage></ri:Resource>
