SudokuPad Color Picker
The SudokuPad colorpicker extension allows you to change colors of puzzles in SudokuPad. This includes line colors, but also other colors in the puzzle are available to edit. Our custom palette is included in the script.
Installation
The extension is a Tampermonkey "user script". You will first need to install tampermonkey and then add this script to it: sp_colors.user.js.
Features
The script automatically detects colors (excl. black and white) from the puzzle svg and adds a toggletip that allows you to customize those colors. Colors can either be set to one of our recommended colors or customized using an oklch color picker. The screenshot was created with https://sudokupad.app/3u2jajc86u.
After editing the colors, it is possible to create a new puzzle link with the updated colors, which makes it convenient to update old puzzles where an editing link is no longer available. You can also import/export the colors from/to your clipboard to use them in the setting tool of your choice.
