• Drag a Dimension: In Tableau, you can change the color of data points by dragging a dimension (a categorical variable) to the "Color" shelf in the Marks card.

3. Edit Colors:

• Color Palette: Tableau provides a default color palette for the dimension you selected. To change the colors, click on the color legend in the Marks card.

• Edit Colors: A "Edit Colors" dialog will open, allowing you to customize the color scheme. You can select predefined color palettes or create your custom color scheme.
