Part 2: How to Color Lineart in Photopea – Step-by-Step Guide

This section explains the complete workflow beginners can follow when learning how to color lineart in Photopea. The method is similar to what you would see in a simple photopea lineart coloring tutorial, but with clearer explanations of why each step matters.

Step 1: Import your lineart into Photopea

Open Photopea in your browser and go to File > Open to select your drawing file.

Photopea supports PSD, PNG, JPG, and other common formats, so you can upload scanned sketches, digital line drawings, or files exported from other tools. Once imported, the lineart appears on its own layer in the Layers panel.

My experience: Uploading a PNG tends to work best because it preserves crisp lines, especially when preparing the artwork for digital coloring.

Step 2: Ensure your lineart is on its own layer

Your lineart should be completely separated from the background. If the drawing includes a white background, remove it or convert the image to a transparent PNG using the Magic Eraser, Select > Remove BG, or other selection tools.

Tip: If you cannot remove the white background easily, you can still proceed by changing the blend mode in the next step.

My experience: Clean, isolated lineart always gives smoother color fills and reduces edge cleanup later.

Step 3: Set the lineart layer to Multiply

With the lineart layer selected, change the blend mode from Normal to Multiply.

This step is essential because Multiply allows colors on layers beneath the lineart to show through without covering the black lines. It is the foundation of the Photopea Multiply coloring method.

My experience: Multiply consistently produces the cleanest results for black linework. It behaves exactly like the mode in Photoshop, so beginners can follow familiar workflows.

Step 4: Create a new layer below the lineart

Go to Layer > New Layer and drag it underneath the lineart layer.

This will become your coloring layer. Keeping layers organized is important because beginners often paint directly on the lineart by mistake.

My experience: Label your layers clearly, such as “Base Colors” or “Shading, to avoid confusion once multiple layers are added.

Step 5: Use the Brush Tool or Paint Bucket to add base colors

Select the Brush Tool (B) for manual painting or the Paint Bucket (G) for quick fills.

Begin adding flat colors on the layer beneath the lineart. If areas spill outside the edges, use the Eraser Tool or selections to clean the boundaries.

If you prefer cleaner fills, lock transparency on a layer after your base colors are established.

My experience: For beginners, brushing works better than buckets because it gives more control and avoids jagged edges, especially when learning how to color black and white drawings online.

Step 6: Final adjustments

Zoom in and clean any rough lines, refine color boundaries, and adjust hue, saturation, or brightness to unify the artwork. Small edits can significantly improve the overall look.

My experience: Beginners often skip this stage, but polished edges and balanced colors make the final illustration look intentional and professional.

• Step 3: Upscale the image for better quality

For blurry or low-resolution sketches, use the AI Upscale tool to increase resolution without losing detail. This helps the lines appear sharper when using digital brushes.

• Step 4: Save and import into Photopea

Export your optimized file and reopen it in Photopea. With enhanced clarity and a clean outline, the coloring process becomes faster and more accurate.

My experience: Using WPS Photos before starting the coloring stage helps reduce cleanup work. Sharper lineart allows smoother fills and cleaner edges, especially when working with scanned sketches or drawings captured with a phone.
