How to Apply a Custom Color Scheme to a PowerPoint Theme

You want to apply a custom color scheme to a PowerPoint theme so your presentation matches your brand or personal style. PowerPoint stores color schemes in XML-based theme files with the .thmx extension. This article explains how to create a custom color scheme from scratch and save it as part of a reusable theme.

What a Custom Color Scheme Does and What You Need Before Starting

A color scheme in PowerPoint is a set of 12 colors: four text and background colors, six accent colors, and two hyperlink colors. These colors are linked to placeholders and shapes so that changing the scheme updates every slide element that uses a theme color. You do not need any special software or coding skills. You need PowerPoint 2016 or later on Windows or Mac. The same steps work on PowerPoint for Microsoft 365. Before you begin, have your brand hex codes or RGB values ready.

Steps to Create and Apply a Custom Color Scheme to a PowerPoint Theme

Method 1: Create a Custom Color Scheme From the Slide Master View

1. Open your presentation and go to Slide Master view
   Click View on the ribbon and then click Slide Master. This opens the master view where all theme elements are edited.
2. Open the Colors menu
   On the Slide Master tab, click the Colors button in the Background group. A drop-down list of built-in color schemes appears.
3. Select Customize Colors
   At the bottom of the drop-down list, click Customize Colors. The Create New Theme Colors dialog opens.
4. Define each color slot
   The dialog shows 12 color slots: Text/Background – Dark 1 and Light 1, Text/Background – Dark 2 and Light 2, Accent 1 through Accent 6, Hyperlink, and Followed Hyperlink. Click the color picker next to each slot to enter a hex code or choose a color from the palette.
5. Name your custom color scheme
   In the Name field at the bottom of the dialog, type a descriptive name such as Company Brand 2025.
6. Save the scheme
   Click Save. The scheme is now available in the Colors menu under Custom.
7. Apply the scheme to the current theme
   Back in Slide Master view, click Close Master View. The custom color scheme is now applied to every slide that uses the theme colors.

Method 2: Save the Entire Theme Including the Custom Color Scheme

1. Create or open a presentation with your custom color scheme applied
   Follow Method 1 to define and apply the scheme first.
2. Go to File > Save As
   Click File, then Save As. Choose a location such as This PC or a cloud folder.
3. Select PowerPoint Template as the file type
   In the Save as type drop-down list, choose PowerPoint Template (.potx).
4. Name and save the template
   Type a file name like Brand Theme and click Save. The .potx file now contains your custom color scheme along with any fonts, effects, and slide layouts you modified.

Method 3: Apply a Saved Custom Color Scheme to a Different Presentation

1. Open the target presentation
   Open the presentation you want to apply the scheme to.
2. Go to the Design tab
   Click Design on the ribbon.
3. Open the Variants gallery
   In the Variants group, click the More arrow (down arrow icon).
4. Hover over Colors
   A sub-menu shows built-in and custom schemes. Your saved scheme appears under Custom at the top of the list.
5. Click the custom scheme name
   The presentation updates all theme-color elements to match your custom colors.

Common Mistakes and Limitations When Applying Custom Color Schemes

Custom color scheme does not appear in the Colors menu

This happens when you save the scheme without closing the Create New Theme Colors dialog properly. Click Save, not Cancel. If the scheme is still missing, restart PowerPoint. Schemes are stored in the registry and may not refresh until the application restarts.

Colors change when you apply the scheme to an existing presentation

Only elements that use theme colors update. Shapes or text with manually chosen colors (not from the theme palette) stay unchanged. To ensure full consistency, use theme color placeholders for all new slides. Select a shape, right-click, choose Fill, and pick a theme color from the palette.

You cannot share a color scheme alone without the theme file

PowerPoint does not export a color scheme as a standalone file. You must save the entire theme as a .potx template. Send the .potx file to colleagues. They can open it and then use Method 3 to apply the scheme to their presentations.

Custom Color Scheme vs Built-in Scheme: Key Differences

Item	Custom Color Scheme	Built-in Scheme
Availability	Appears under Custom in the Colors menu after creation	Listed by default in the Colors menu
Portability	Must be saved inside a .potx template to share	Always available on any installation of PowerPoint
Modification	Editable via Customize Colors at any time	Cannot be edited; you must duplicate and then customize
Brand alignment	Matches exact brand hex codes	Uses generic Office defaults

You can now create a custom color scheme, save it as part of a PowerPoint theme, and apply it to any presentation. Next, try pairing your scheme with custom fonts using View > Slide Master > Fonts > Customize Fonts. For advanced branding, open the XML inside the .thmx file to define color variants for dark mode presentations.
