@iyyb930,
Thank you for posting the inquiry.

You can get and set any theme colors. Please read the following documentation page: Presentation Theme. If the issue persists, please describe your goal in more detail.

This document also only introduces 13 theme colors such as dark1 accent1, etc., but there are more theme colors generated according to the rules below each theme color. How to get and set it here?image.png (108.1 KB)

As shown in the figure, I used the following colors derived from the theme color, and then he also received the control of the theme color change in powerpoint. How to obtain this similar theme colorimage.jpg (97.3 KB)

@iyyb930,
To properly understand the issue, please share a presentation file created in PowerPoint that contains objects with the desired view.

The shapes in the file are filled with the derived theme color

@iyyb930,
Thank you for the additional information. I performed some research and found no way to do this. I’ve added a ticket with ID SLIDESJAVA-38702 in our issue tracking system and described your requirements. Our development team will consider implementing such a feature. You will be notified when the issue is resolved.

@iyyb930,
Our development team investigated the issue. The colors from the additional palette are formed by applying Luminance transformations to the main color. Please try the following code example:

Presentation presentation = new Presentation();
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    // Accent 4
    IShape shape1 = slide.getShapes().addAutoShape(ShapeType.Rectangle, 10, 10, 50, 50);

    shape1.getFillFormat().setFillType(FillType.Solid);
    shape1.getFillFormat().getSolidFillColor().setSchemeColor(SchemeColor.Accent4);

    // Accent 4, Lighter 80%
    IShape shape2 = slide.getShapes().addAutoShape(ShapeType.Rectangle, 10, 70, 50, 50);

    shape2.getFillFormat().setFillType(FillType.Solid);
    shape2.getFillFormat().getSolidFillColor().setSchemeColor(SchemeColor.Accent4);
    shape2.getFillFormat().getSolidFillColor().getColorTransform().add(ColorTransformOperation.MultiplyLuminance, 0.2f);
    shape2.getFillFormat().getSolidFillColor().getColorTransform().add(ColorTransformOperation.AddLuminance, 0.8f);

    // Accent 4, Lighter 60%
    IShape shape3 = slide.getShapes().addAutoShape(ShapeType.Rectangle, 10, 130, 50, 50);

    shape3.getFillFormat().setFillType(FillType.Solid);
    shape3.getFillFormat().getSolidFillColor().setSchemeColor(SchemeColor.Accent4);
    shape3.getFillFormat().getSolidFillColor().getColorTransform().add(ColorTransformOperation.MultiplyLuminance, 0.4f);
    shape3.getFillFormat().getSolidFillColor().getColorTransform().add(ColorTransformOperation.AddLuminance, 0.6f);

    // Accent 4, Lighter 40%
    IShape shape4 = slide.getShapes().addAutoShape(ShapeType.Rectangle, 10, 190, 50, 50);

    shape4.getFillFormat().setFillType(FillType.Solid);
    shape4.getFillFormat().getSolidFillColor().setSchemeColor(SchemeColor.Accent4);
    shape4.getFillFormat().getSolidFillColor().getColorTransform().add(ColorTransformOperation.MultiplyLuminance, 0.6f);
    shape4.getFillFormat().getSolidFillColor().getColorTransform().add(ColorTransformOperation.AddLuminance, 0.4f);

    // Accent 4, Darker 25%
    IShape shape5 = slide.getShapes().addAutoShape(ShapeType.Rectangle, 10, 250, 50, 50);

    shape5.getFillFormat().setFillType(FillType.Solid);
    shape5.getFillFormat().getSolidFillColor().setSchemeColor(SchemeColor.Accent4);
    shape5.getFillFormat().getSolidFillColor().getColorTransform().add(ColorTransformOperation.MultiplyLuminance, 0.75f);

    // Accent 4, Darker 50%
    IShape shape6 = slide.getShapes().addAutoShape(ShapeType.Rectangle, 10, 310, 50, 50);

    shape6.getFillFormat().setFillType(FillType.Solid);
    shape6.getFillFormat().getSolidFillColor().setSchemeColor(SchemeColor.Accent4);
    shape6.getFillFormat().getSolidFillColor().getColorTransform().add(ColorTransformOperation.MultiplyLuminance, 0.5f);

    presentation.save("example_accent4.pptx", SaveFormat.Pptx);
} finally {
    if (presentation != null) presentation.dispose();
}
