Unable to change color of text element

Using an object of type IShape named shape,

shape.FillFormat.SolidFillColor.Color = System.Drawing.Color.Red;

Does not change the color property.

I am currently experimenting with the trial version. Is there a trial version limitation on setting color values?


I have observed your comments. Can you please share sample project and source presentation so that we may further investigate to help you out. Also please share environment details along with version of Aspose.Slides so that we may help you out.

I am on windows 10 aspose version 17.12.1
Attached is a sample winforms application. It will open a presentation, attempt to change colors, then save to a new file in same directory.
