Question details
The user wants to know how to change the fill color and border color of specific objects within an existing PDF document.

- Product
- Device & OS
- not provided
- Scenario
- Modifying the appearance of specific vector objects or shapes in a PDF document when color controls are not immediately visible.
- Observed behavior
- The color controls in the PDF editor are hidden or the shapes are difficult to select and recolor separately, prompting the need for advanced editing or workarounds.
Before attempting to edit shapes directly in a PDF, check if you have access to the original source file (such as a Word or PowerPoint document). It is usually much faster and easier to change colors in the original application and re-export the PDF.
Edit Object Colors Directly in the PDF Editor
Use the standard object editing tools in your PDF application to select the border and fill separately, then modify their properties.
In many PDF documents, borders and fills might be structured as separate, overlapping objects rather than a single unified shape. This can make selecting the fill difficult if the border is in the way.
Open your PDF editor and activate the 'Edit' or 'Edit Object' tool to make individual elements in the document selectable.
Click on the border of the object to select it. Look for the color control options, which are usually located in the right-hand properties pane or near the formatting settings.
If the fill and border are separate overlapping objects, click and drag the border temporarily to the side so you can click and select the fill object underneath.
Modify the fill color as desired. Once the new color is applied, drag the border back into its original position over the fill.

Edit the Object with a Vector Graphics Editor
If the objects are embedded as complex vectors or images that a standard PDF editor cannot easily recolor, open them in Adobe Illustrator.
Replace the Object with a New Shape
If editing the original object is too difficult or impossible, create a new object with the correct colors and place it over the old one.
Easily Edit PDF Objects and Shapes with WPS Office
WPS PDF provides an intuitive interface for editing text, images, and shapes directly within your PDF documents, saving you from needing complex secondary design software.
- 1. Open your PDF file: Launch WPS Office and open the PDF document you need to edit.
- 2. Enable object editing: Navigate to the 'Edit' tab and click on the 'Edit Content' button to make all document objects selectable.
- 3. Select the shape: Click directly on the shape or object whose colors you want to modify.
- 4. Change colors: Use the 'Shape Appearance' panel on the right side of the screen to quickly adjust the fill color and border color.

Frequently Asked Questions
Why can't I select the fill and border separately in my PDF?
Sometimes shapes are grouped together or rendered as a single flat image. If they are separate overlapping objects, they might be stacked tightly. Try moving the top object (the border) temporarily to select the fill object underneath.
Can I change the color of an image object in a PDF?
Standard PDF editors generally cannot change the colors inside a raster image (like a JPEG or PNG) that is embedded in a PDF. If the colors belong to an image rather than a vector shape, you will need to extract the image, edit it in a photo editor like Photoshop, and then insert it back into the PDF.
Why is there no color control option when I select a PDF object?
The object might have been flattened during the PDF export process, or it is not recognized as a modifiable vector shape by your current PDF editor. In such cases, replacing the object with a new shape or editing the original source file (like Word or PowerPoint) is the best approach.
What is the easiest way to change PDF object colors if I don't have Adobe Acrobat?
You can use an alternative PDF editor like WPS PDF, which allows you to edit shapes natively. Alternatively, if you have the original source document (such as a Word document), you can open it, change the shape colors there, and export it as a new PDF.
