To select all pixels of one color in Photopea, the most effective tool is the Magic Wand.
The Magic Wand is designed specifically for selecting pixels based on their color. According to the reference, the Magic Wand allows you to select pixels with the same (or similar) color. Once you click somewhere with the Magic Wand, the pixel under the mouse will be selected, as well as all other pixels, that have a color similar to that pixel. This makes it ideal for isolating areas of a consistent color.
Using the Magic Wand Tool
Here's how you can use the Magic Wand in Photopea to select pixels of a specific color:
- Select the Tool: In the Photopea toolbar, find and click the Magic Wand tool. It typically looks like a wand with a sparkling tip. You might find it grouped with other selection tools like the Quick Selection tool; click and hold the icon to reveal the Magic Wand if it's not immediately visible.
- Adjust Settings: Before clicking, look at the options bar at the top of the Photopea window. Key settings include:
- Tolerance: This determines how "similar" a color needs to be to the one you click on to be included in the selection. A higher tolerance selects a wider range of colors; a lower tolerance selects only very similar colors.
- Contiguous: When checked, the selection will only include pixels of similar color that are connected to the pixel you clicked. When unchecked, it will select all pixels of a similar color throughout the entire layer, regardless of whether they are connected or not. For selecting all pixels of a color across the image, ensure Contiguous is unchecked.
- Anti-alias: Smoothes the edges of the selection.
- Select: Options like 'New selection', 'Add to selection', 'Subtract from selection', and 'Intersect with selection' affect how new clicks interact with existing selections. Use 'New selection' to start, or 'Add to selection' if you need to select multiple distinct color areas.
- Click on the Color: Click directly on a pixel of the color you want to select. If Contiguous is unchecked, all pixels matching the tolerance throughout the layer will be selected.
Understanding Tolerance
Tolerance is crucial for getting the selection you want.
| Tolerance Setting | Effect | Use Case |
|---|---|---|
| Low (e.g., 0-10) | Selects only pixels extremely close to the clicked color. | Selecting very specific, uniform color blocks. |
| Medium (e.g., 10-50) | Selects a moderate range of similar colors. | Selecting solid colors with minor variations. |
| High (e.g., 50+) | Selects a wide range of colors around the clicked point. | Selecting areas with gradients or subtle color shifts. |
Experimenting with the Tolerance level might be necessary to get the exact selection you need, especially if the color isn't perfectly uniform.
Pro Tips
- Make sure you have the correct layer selected in the Layers panel.
- If the color is on multiple layers, you might need to either merge layers or select pixels on each layer individually.
- To refine your selection after using the Magic Wand, you can use other selection tools in 'Add to selection' or 'Subtract from selection' mode, or use the 'Select and Mask' feature.
By using the Magic Wand and adjusting its settings, particularly Tolerance and Contiguous, you can efficiently select pixels of a specific color (or similar colors) in your Photopea project.
