Question 1

How does the tool count colors in my pixel art?

Accepted Answer

This tool utilizes the HTML5 Canvas API to process your image at a pixel-by-pixel level. It iterates through the entire image data array, extracting the RGBA values of every pixel and filtering them through a Set data structure to ensure only unique colors are counted. This allows for precise calculation even in complex, high-resolution sprites.

Because the entire process happens within your browser's memory, there is no server-side communication or file uploading. Your image data never leaves your computer, ensuring total privacy and near-instant processing speeds, regardless of the complexity of your pixel art file.

Question 2

Why is sorting by hue important for pixel art?

Accepted Answer

Sorting colors by hue is essential for organizing a sprite sheet or a game’s color palette, especially when working with indexed colors. By grouping similar colors together, artists can identify redundant shades, maintain consistency across character animations, and ensure that light and shadow transitions remain smooth and visually logical.

Beyond hue, our tool supports sorting by luminance and saturation, which helps identify color ramps and tonal balance. This is particularly useful for optimizing game assets to fit within strict memory budgets or to match a specific artistic direction for UI and background elements.

Question 3

Is this application safe and secure to use?

Accepted Answer

Yes, this tool is designed with a security-first, client-side architecture. It does not use cookies, localStorage, or any database to store your data. When you refresh the page or close the tab, all image data and color information are permanently purged from the browser's volatile memory.

Since the application is strictly self-contained within one file and runs in a sandboxed environment, there is no risk of cross-site scripting or unauthorized data tracking. You can use it confidently for proprietary game assets, personal fan art, or professional design work.

Question 4

Can I export the palettes I generate?

Accepted Answer

Absolutely. Once the tool has analyzed and sorted your colors, you can export the palette in multiple developer-friendly formats. We provide direct support for JSON, CSS variables, and raw text lists, making it easy to integrate the colors directly into your game engines, stylesheet files, or design software.

Additionally, each color swatch in the results grid allows for a one-click copy of the HEX or RGB value to your clipboard. This ensures a seamless transition from analysis to implementation, saving you valuable time during the sprite-creation and asset-management phase of your development workflow.
