## **Introduction**

A presentation theme defines the properties of design elements. When you select a presentation theme, you are essentially choosing a specific set of visual elements and their properties.

In PowerPoint, a theme comprises colors, [fonts](/slides/androidjava/powerpoint-fonts/), [background styles](/slides/androidjava/presentation-background/), and effects.

## **Change Theme Color**

A PowerPoint theme uses a specific set of colors for different elements on a slide. If you don't like the colors, you change them colors by applying new colors for the theme. To allow you select a new theme color, Aspose.Slides provides values under the [SchemeColor](https://reference.aspose.com/slides/androidjava/com.aspose.slides/SchemeColor) enumeration.

This Java code shows you how to change the accent color for a theme:

```java
import com.aspose.slides.*;

Presentation pres = new Presentation();
try {
    IAutoShape shape = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 10, 10, 100, 100);

    shape.getFillFormat().setFillType(FillType.Solid);

    shape.getFillFormat().getSolidFillColor().setSchemeColor(SchemeColor.Accent4);
} finally {
    if (pres != null) pres.dispose();
}
```

You can determine the resulting color's effective value this way:

```java
import com.aspose.slides.*;
import java.awt.Color;

Presentation pres = new Presentation();
try {
    IAutoShape shape = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 10, 10, 100, 100);

    shape.getFillFormat().setFillType(FillType.Solid);

    shape.getFillFormat().getSolidFillColor().setSchemeColor(SchemeColor.Accent4);

    IFillFormatEffectiveData fillEffective = shape.getFillFormat().getEffective();

    Color effectiveColor = fillEffective.getSolidFillColor();

    System.out.println(String.format("Color [A=%d, R=%d, G=%d, B=%d]",
            effectiveColor.getAlpha(), effectiveColor.getRed(), effectiveColor.getGreen(), effectiveColor.getBlue()));
} finally {
    if (pres != null) pres.dispose();
}
```

To further demonstrate the color change operation, we create another element and assign the accent color (from the initial operation) to it. Then we change the color in the theme:

```java
import com.aspose.slides.*;
import java.awt.Color;

Presentation pres = new Presentation();
try {
    IAutoShape otherShape = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 10, 120, 100, 100);

    otherShape.getFillFormat().setFillType(FillType.Solid);

    otherShape.getFillFormat().getSolidFillColor().setSchemeColor(SchemeColor.Accent4);

    pres.getMasterTheme().getColorScheme().getAccent4().setColor(Color.RED);
} finally {
    if (pres != null) pres.dispose();
}
```

The new color is applied automatically on both elements.

### **Set Theme Color from an Additional Palette**

When you apply luminance transformations to the main theme color(1), colors from the additional palette(2) are formed. You can then set and get those theme colors. 

![additional-palette-colors](additional-palette-colors.png)

**1** - Main theme colors

**2** - Colors from the additional palette.

This Java code demonstrates an operation where additional palette colors are obtained from the main theme color and then used in shapes:

```java
import com.aspose.slides.*;

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();
}
```

### **Map `SchemeColor` to `IColorScheme` Colors**

When you work with [SchemeColor](https://reference.aspose.com/slides/androidjava/com.aspose.slides/schemecolor/), you may notice that it contains the following theme color values:

`Background1`, `Background2`, `Text1`, and `Text2`.

However, `Presentation.getMasterTheme().getColorScheme()` returns [IColorScheme](https://reference.aspose.com/slides/androidjava/com.aspose.slides/icolorscheme/), which exposes the corresponding colors as:

`Dark1`, `Dark2`, `Light1`, and `Light2`.

This difference is only in naming. These values refer to the same theme color slots and the mapping is fixed:

* `Text1` = `Dark1`
* `Background1` = `Light1`
* `Text2` = `Dark2`
* `Background2` = `Light2`

There is no dynamic conversion between `Text`/`Background` and `Dark`/`Light`. They are simply alternate names for the same theme colors.

This naming difference comes from Microsoft Office terminology. Older Office versions used `Dark 1`, `Light 1`, `Dark 2`, and `Light 2`, while newer UI versions display the same slots as `Text 1`, `Background 1`, `Text 2`, and `Background 2`.

## **Change Theme Font**

To allow you select fonts for themes and other purposes, Aspose.Slides uses these special identifiers (similar to those used in PowerPoint):

* **+mn-lt** - Body Font Latin (Minor Latin Font)
* **+mj-lt** -Heading Font Latin (Major Latin Font)
* **+mn-ea** - Body Font East Asian (Minor East Asian Font)
* **+mj-ea** - Body Font East Asian (Major East Asian Font)

This Java code shows you how to assign the Latin font to a theme element:

```java
import com.aspose.slides.*;

Presentation pres = new Presentation();
try {
    IAutoShape shape = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 10, 10, 100, 100);

    Paragraph paragraph = new Paragraph();

    Portion portion = new Portion("Theme text format");

    paragraph.getPortions().add(portion);

    shape.getTextFrame().getParagraphs().add(paragraph);

    portion.getPortionFormat().setLatinFont(new FontData("+mn-lt"));
} finally {
    if (pres != null) pres.dispose();
}
```

This Java code shows you how to change the presentation theme font:

```java
import com.aspose.slides.*;

Presentation pres = new Presentation();
try {
    pres.getMasterTheme().getFontScheme().getMinor().setLatinFont(new FontData("Arial"));
} finally {
    if (pres != null) pres.dispose();
}
```

The font in all text boxes will be updated.

## **Change Theme Background Style**

By default, the PowerPoint app provides 12 predefined backgrounds but only 3 from those 12 backgrounds are saved in a typical presentation. 

![todo:image_alt_text](presentation-design_8.png)

For example, after you save a presentation in the PowerPoint app, you can run this Java code to find out the number of predefined backgrounds in the presentation:

```java
import com.aspose.slides.*;

Presentation pres = new Presentation("pres.pptx");
try {
    int numberOfBackgroundFills = pres.getMasterTheme().getFormatScheme().getBackgroundFillStyles().size();

    System.out.println("Number of background fill styles for theme is " + numberOfBackgroundFills);
} finally {
    if (pres != null) pres.dispose();
}
```

{{% alert color="warning" %}} 

Using the [BackgroundFillStyles](https://reference.aspose.com/slides/androidjava/com.aspose.slides/FormatScheme#getBackgroundFillStyles--) property from the [FormatScheme](https://reference.aspose.com/slides/androidjava/com.aspose.slides/FormatScheme) class, you can add or access the background style in a PowerPoint theme.

{{% /alert %}} 

This Java code shows you how to set the background for a presentation:

```java
import com.aspose.slides.*;

Presentation pres = new Presentation("pres.pptx");
try {
    pres.getMasters().get_Item(0).getBackground().setStyleIndex(2);
} finally {
    if (pres != null) pres.dispose();
}
```

**Index guide**: 0 is used for no fill. The index starts from 1.

{{% alert color="primary" title="TIP" %}} 

You may want to see [PowerPoint Background](/slides/androidjava/presentation-background/).

{{% /alert %}}

## **Change Theme Effect**

A PowerPoint theme usually contains 3 values for each style array. Those arrays are combined into these 3 effects: subtle, moderate, and intense. For example, this is the outcome when the effects are applied to a specific shape:

![todo:image_alt_text](presentation-design_10.png)



Using 3 properties ([FillStyles](https://reference.aspose.com/slides/androidjava/com.aspose.slides/FormatScheme#getFillStyles--), [LineStyles](https://reference.aspose.com/slides/androidjava/com.aspose.slides/FormatScheme#getLineStyles--), [EffectStyles](https://reference.aspose.com/slides/androidjava/com.aspose.slides/FormatScheme#getEffectStyles--)) from the  [FormatScheme](https://reference.aspose.com/slides/androidjava/com.aspose.slides/FormatScheme) class you can change the elements in a theme (even more flexibly than the options in PowerPoint).

This Java code shows you how to change a theme effect by altering parts of elements:

```java
import com.aspose.slides.*;
import java.awt.Color;

Presentation pres = new Presentation("Subtle_Moderate_Intense.pptx");
try {
    pres.getMasterTheme().getFormatScheme().getLineStyles().get_Item(0).getFillFormat().getSolidFillColor().setColor(Color.RED);

    pres.getMasterTheme().getFormatScheme().getFillStyles().get_Item(2).setFillType(FillType.Solid);

    pres.getMasterTheme().getFormatScheme().getFillStyles().get_Item(2).getSolidFillColor().setColor(Color.GREEN);

    pres.getMasterTheme().getFormatScheme().getEffectStyles().get_Item(2).getEffectFormat().getOuterShadowEffect().setDistance(10f);

    pres.save("Design_04_Subtle_Moderate_Intense-out.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}
```

The resulting changes in fill color, fill type, shadow effect, etc:

## **FAQ**

### Can I apply a theme to a single slide without changing the master?

Yes. Aspose.Slides support slide-level theme overrides, so you can apply a local theme to just that slide while keeping the master theme intact (via the [SlideThemeManager](https://reference.aspose.com/slides/androidjava/com.aspose.slides/slidethememanager/)).

### What’s the safest way to carry a theme from one presentation to another?

[Clone slides](/slides/androidjava/clone-slides/) together with their master into the target presentation. This preserves the original master, layouts, and the associated theme so the appearance remains consistent.

### How can I see the "effective" values after all inheritance and overrides?

Use the API’s ["effective" views](/slides/androidjava/shape-effective-properties/) for theme/color/font/effect. These return the resolved, final properties after applying the master plus any local overrides.
