How to filter based on Colour in sharepoint

ikarafi Unfortunately, you cannot filter based on color which is applied using JSON formatting.

SharePoint JSON formatting only customizes how columns in SharePoint lists and libraries are displayed, it does not store any value/information (color) in list.

So, you cannot filter the list items based on colors/values added using conditional JSON formatting.

You have to apply the same logic you used for JSON formatting in your list view filter settings. Follow documentation: Use filtering to modify a SharePoint view
