How to add a color overlay to an animation in Lottie?

When working with Lottie for animation, adding a color overlay can make the animation better match visual requirements, especially when adjusting it to fit different brands or themes. Below, I'll detail the specific methods for adding a color overlay in Lottie:

1. Using the LottieFiles Editor

LottieFiles offers an online editor that allows you to modify Lottie animations directly in your browser. Here are the steps to add a color overlay using the LottieFiles editor:

1. Upload the animation: First, upload your Lottie JSON file to the LottieFiles editor at LottieFiles.
2. Select the layer: After uploading, you can view all the layers of the animation. Select the layer where you want to apply the color overlay.
3. Adjust the color: In the layer properties, locate the color adjustment section. Use the color picker to choose a new color, which will be applied as the overlay to the selected layer.
4. Save and download: After making adjustments, save the changes and download the updated Lottie file.

2. Coding Approach

If you're familiar with coding, you can directly modify the Lottie animation's JSON file to add a color overlay. This typically involves adjusting the color properties of specific layers. For example:

json
{
  "layers": [
    {
      "nm": "Layer Name",
      "ty": 4,
      "shapes": [
        {
          "it": [
            {
              "ty": "fl",
              "c": {
                "k": [
                  [0, 1, 1, 1, 1]  // RGBA color values
                ]
              }
            }
          ]
        }
      ]
    }
  ]
}

In this JSON structure, the "c" key represents the color, and the value [0, 1, 1, 1, 1] denotes RGBA. Adjust these values as needed to change the color.

3. Practical Application

For example, in a project, we needed to adapt a Lottie animation originally designed for summer events to suit autumn. The original animation primarily used light blue and yellow colors. To match the autumn theme, we used the LottieFiles editor to adjust the colors to orange and brown, completing the brand theme adaptation quickly with just a few simple steps.

Conclusion

Using the LottieFiles editor is a quick and intuitive method, ideal for users who prefer not to work with code. If you require more granular control, modifying the JSON file is a good option. With these methods, you can flexibly add color overlays to Lottie animations to better align with various visual requirements.
