Adding custom colors to Google Slides transforms a standard presentation into a polished and brand-consistent visual experience. Whether you are aligning with a company style guide or simply trying to make your slides more visually engaging, defining your own color palette is a crucial step.

Unlike basic theme colors, custom colors give you precise control over hex codes, ensuring that the exact shade you envision appears exactly as intended. This guide walks you through the process of adding these colors to your palette and applying them throughout your deck.

Understanding the Color Palette Limit
Before diving into the steps, it is important to understand how Google Slides handles color management. The platform allows users to define a specific number of custom colors that are saved directly within your Google account for use in Slides and other apps like Docs and Sheets.

While you can technically create an unlimited number of palettes, the system relies on a standard set of swatch slots. Knowing this limitation helps you manage your colors efficiently and avoid cluttering your palette with hues you no longer use.
Step-by-Step: Adding a New Color

To add your specific shade, you need to access the color picker in a way that allows saving the selection. The process is designed to be intuitive once you know where to look.
Accessing the Custom Menu
Begin by selecting a text box or a shape on your slide. Click on the text color or shape outline icon in the toolbar to open the formatting menu. To save a color for future use, you must choose the "Custom" option rather than one of the preset theme colors.

Using the Hex Code
The most accurate method to add custom colors to Google Slides is by entering a hexadecimal color code. In the color dialog box, locate the field labeled "Hex" and input the six-digit code representing your desired color (for example, #FF5733 for a vibrant orange). As you type, the color preview will update in real-time, allowing for precise adjustments.
| Color Type | When to Use |
|---|---|
| Theme Colors | For quick, basic changes that match Google’s standard palette. |
| Custom Colors | For brand consistency and specific design requirements. |
| Standard Colors | For rapid formatting without opening the color wheel. |

Managing Your Saved Palette
Once you have added a custom color, it does not disappear after you close the dialog box. Google Slides saves these hues to your account, making them available the next time you open the editor.




















To view your saved colors, simply open the color picker again and look at the bottom section of the sidebar or the top row of the palette. These saved colors appear as distinct swatches, ready to be applied to any element in your presentation.
Best Practices for Color Application
Adding the color is only half the battle; using it effectively is what truly impacts your audience. Consistency is key when working with a custom palette.
Designate specific colors for specific purposes. For example, use one custom color for headings, another for data visualization, and a third for background accents. This structure helps maintain a professional look and ensures that your slides are easy to read.
Removing or Editing Old Colors
Over time, your saved palette might include colors that are no longer relevant to your current projects. Google Slides allows you to manage this list to keep it streamlined.
To remove a color, open the color picker, locate the specific swatch you wish to delete, and simply click the "X" or trash icon that appears over it. This action removes the color only from your saved list and does not affect the slides where it was already used; those slides will revert to a standard theme color.
Syncing Across Devices
Because custom colors are tied to your Google account, they sync automatically across your laptop, tablet, and phone. This means that if you add a new color on your desktop editor, you can immediately access that exact shade in the Slides app during a meeting.
Ensure you are logged into the same account on all devices to maintain a consistent visual identity no matter where you are presenting.
