I have a point layer representing bird sightings. Each sighting has a survey date associated with it. I am trying to figure out a way to have QGIS display these point in a way that each date has a distinct colour. E.g. all birds seen 18/03/22 might be green but all sightings on 21/03/22 would be blue. Short of creating a colour for every date of the year I cannot seem to find a way to do this?
You have the categorized style in the symbology properties. You don't need to create one for every day, you can use the "Classify" bottom and QGIS do it for you, giving random colours to each date. If you don't want the random colours you can choose a color ramp.
