I can still do this in 3.3 but the layout does not honour the greyscale and shows full colour. I read a post about adding to a group and applying luminosity and transparency there but it does not work on these base maps.</P><P>Any suggestions most welcomed</P> Wed, 09 Apr 2025 08:21:52 GMT https://community.esri.com/t5/arcgis-pro-questions/layout-in-3-3-not-honouring-greyscale-base-map/m-p/1604085#M94773 MarkYoung 2025-04-09T08:21:52Z https://community.esri.com/t5/arcgis-pro-questions/layout-in-3-3-not-honouring-greyscale-base-map/m-p/1604147#M94775 <P>Found the answer - map properties and set the background to white</P> Wed, 09 Apr 2025 12:50:40 GMT https://community.esri.com/t5/arcgis-pro-questions/layout-in-3-3-not-honouring-greyscale-base-map/m-p/1604147#M94775 MarkYoung 2025-04-09T12:50:40Z
