GUIDE 1
Open Mystery Color Maker
How to use Mystery Color Maker
Turn a clear photo or illustration into a numbered mystery page, a completed answer, an exact palette, and files ready for online coloring.
Select a creation mode
Mosaic makes regular geometric cells. Artistic uses organic cells that follow the image. Monochrome by Shapes creates a one-color hidden-image puzzle.
Choose the page size
Select the final print format: US Letter, square, 8 × 10, 6 × 9, large square, workbook, or A4.
Set the difficulty
Easy uses larger, simpler areas. Medium balances detail and readability. Detailed creates more cells for an advanced page.
Adjust cells and colors
For Mosaic or Monochrome, choose a cell shape. For a multicolor project, select the number of colors and the palette style.
Make numbers readable
Choose the printed number size and color. Use larger numbers when the page is intended for children, seniors, or small-format printing.
Generate the project
Use a single-creation pass or sign in and use one account credit. A credit is charged only after the complete project is generated successfully.
Download or color online
When generation finishes, download the ZIP. It contains the mystery page, colored answer, official palette, and coloring data. If Color Your Project is available, open it directly in the online colorer.

Color the matching cells

Use the mouse wheel to zoom and drag to pan. Fit shows the whole page, while Focus and Full Screen give you more coloring space.
Correct or speed up your work
Use Undo for the last action or Reset to start again. Fill selected and Fill recognized are faster options when you want automatic progress.
