How to Invert Colors in Paint.NET

Inverting the colors of an image layer in Paint.NET is a quick and simple process that replaces every color on the canvas with its exact photographic negative. Whether you are creating stylized graphics, designing inverted color schemes, or working with mask channels, this guide explains how to invert the colors of an entire layer or a specific selection using the application's built-in adjustments and keyboard shortcuts.

Steps to Invert Colors on a Layer

  1. Select the Target Layer: Open your project in Paint.NET. Locate the Layers panel on the bottom-right of your screen and click on the specific layer you want to invert to ensure it is active.
  2. Access the Adjustments Menu: Navigate to the top menu bar and click on the Adjustments tab.
  3. Select Invert Colors: From the drop-down menu, click on Invert Colors.

The colors on the selected layer will immediately reverse (e.g., black becomes white, blue becomes orange, and red becomes cyan).

Using the Keyboard Shortcut

To speed up your workflow, Paint.NET includes a dedicated keyboard shortcut for color inversion:

  • Press Ctrl + Shift + I on Windows.

Pressing this key combination immediately inverts the active layer without opening the top menu.

How to Invert a Specific Area

If you do not want to invert the entire layer, you can limit the effect to a designated area:

  1. Choose a selection tool from the Tools panel, such as the Rectangle Select, Lasso Select, or Magic Wand.
  2. Highlight the specific region of the layer you wish to invert.
  3. Apply the inversion by selecting Adjustments > Invert Colors or by pressing Ctrl + Shift + I. Only the pixels inside the active selection outline will be inverted, leaving the rest of the layer untouched.
