Hi,
The colors of the 3-D ellipsoids are assigned based on the grouping parameter color settings.
If you need to change the color of the ellipsoids, select the grouping column in your table, right-click on the header, select Column Properties > Value Colors, and change the color associated with each level according to your preference. You may use a preset color scheme if you have many levels in your grouping variable.
Let us know if this is what you were looking for.
Best regards,
TS
