Blue Marble for Wplace
Install, configure, and use the Blue Marble template overlay on wplace.live
Follow a manual, color-by-color workflow with visual guides, coordinates, and a Wplace-ready template
What is Wplace & Blue Marble?
Understanding the platform and the third-party overlay described in this guide
Wplace.live
A collaborative pixel art canvas where thousands of users create artwork together. Each user places colored pixels with cooldown timers, making precision and coordination essential.
Think of it as a massive digital canvas where everyone contributes to building images, logos, and art pieces in real-time.
Blue Marble
A third-party browser userscript that overlays template images directly onto the Wplace canvas with positioning controls and coordinate displays.
Think of it as digital tracing paper with a grid reference: the image guides manual placement but does not place pixels for you.
What the overlay helps you control
Practical controls for following a template while placing pixels manually
Position a transparent reference image over the correct canvas coordinates.
Filter the overlay to one palette color so dense templates are easier to read.
Use the guide as a reference; Blue Marble does not automate pixel placement.
Template Overlay
PNG/WEBP image overlay with adjustable opacity and positioning
Coordinate System
Precise tile and pixel coordinates for perfect placement
Smart Eyedropper
Enhanced color palette with template color matching
Team Coordination
Share coordinates for seamless collaboration
Progress Tracking
Monitor level progress for optimal timing strategies
Cross-Platform
Availability depends on browser, userscript manager, device, and release
Capabilities & Limitations
Clear expectations for professional use
What Blue Marble Does
What Blue Marble Does NOT Do
Use third-party scripts carefully
Blue Marble is a third-party userscript, not a feature of Wplace Toolkit or Wplace.live. Review the source and release notes before installing it, download only from the linked project repository, and check the current Wplace rules yourself. This guide does not guarantee compatibility or approval by Wplace.live.

Template Setup Guide
Prepare dimensions, transparency, colors, and coordinates before loading the file
Template Setup Steps
- 1
Find the top-left corner coordinates
Fill in Tl X, Tl Y, Px X, and Px Y with the precise coordinates. Use the "Pin" icon to auto-fill after clicking the target pixel.
- 2
Upload your template image
Supports PNG or WEBP formats with transparency support.
- 3
Click the "Create" button
Blue Marble will process and display your template overlay.
- 4
Enable the overlay if needed
If your template doesn't appear, try clicking the "Enable" button.
Template Requirements
Transparent Pixels
- For "any color" pixels: Use transparent in your template
- For "Transparent" color pixels: Use
#defacehex color
Coordinate System
Wplace uses a unique tile-based coordinate system. Each pixel has both tile coordinates and pixel coordinates within that tile.
Tip: Click any pixel on the canvas to see both coordinate systems displayed by Blue Marble.
Image Sizing
Blue Marble displays templates at actual size. A 500×300 pixel image will appear as 500×300 pixels on the canvas.
Repeatable workflow
A preparation and verification sequence you can repeat for each template
Image Preparation
Format & Optimization
- Convert to PNG/WEBP with transparency
- Match dimensions to target canvas area
- Optimize colors for wplace.live palette
Quality Control
- Ensure pixel-perfect scaling
- Test transparency levels
- Verify color accuracy
Template Implementation
Upload & Position
- Load template through Blue Marble interface
- Use coordinate system for precise placement
- Adjust opacity for optimal visibility
Execution Strategy
- Start with outlines and key features
- Use eyedropper for color matching
- Monitor progress tracking for timing
Prepare a reliable Wplace template
Blue Marble works best when the source image already uses the correct palette, scale, and transparency.

Frequently Asked Questions
Practical answers to installation and overlay questions
How can I check the userscript before installing it?
Open the linked GitHub repository, compare the release file with the source in the
src/ folder, review the permissions requested by the userscript, and check recent release notes and issues. Install only if you understand and accept those permissions. Wplace Toolkit does not publish or independently audit the Blue Marble releases.
Why are some pixels not showing on the overlay?
This usually happens if the template image is not converted to the Wplace color palette. You should convert your template using a color converter for Wplace or manually adjust the template image to match the Wplace color palette. Also check that no pixels are disabled in the filter settings of the Blue Marble menu.
How can Blue Marble place pixels for me?
It can't. Unfortunately Blue Marble will not support the automatic placement of pixels without user interaction because it is not allowed by Wplace. Blue Marble is a visual assistance tool only.
How do I hide the overlay?
You can temporarily hide the overlay by clicking the "Disable" button in the Blue Marble menu. If you want to completely remove both the overlay and the Blue Marble menu, turn off the userscript in Tampermonkey and refresh the page.
How do I tell colors apart?
Find the color in the color filter list and click the checkbox to turn the color on or off. If you want to work on only one color at a time (recommended), click "Disable All" in the color filter, then enable the checkbox next to the color you want to place. This way only one color on your template will appear at a time.
How do I get the color of a pixel?
Use the eyedropper in the palette menu of wplace. If your template colors match the wplace palette, you can select the template pixel dot to get the template's color for that pixel.
Why do game notifications appear on top of the overlay?
Game notifications only appear when they need immediate attention. Therefore they have priority over the overlay (which typically needs no attention).
Can I use this on mobile devices?
Mobile support depends on the browser, userscript manager, operating system, and current Blue Marble release. Check the project release notes first; if your browser cannot run userscripts, use the desktop workflow instead.
What image formats are supported?
Blue Marble supports PNG and WEBP formats with transparency. These formats provide the best quality and flexibility for template overlays while maintaining small file sizes.
Ready to set up the overlay?
Review the installation steps, prepare a palette-safe template, and keep placement manual.
