Why Use a Custom Color Palette?

A custom color palette tool is essential for designers, developers, and artists who need to maintain strict brand consistency or create specific aesthetic styles. By forcing an image to use only a predefined set of colors, you can achieve unique visual effects, prepare assets for restricted-color displays, or simply unify the look of a large batch of images.

Design Consistency

Ensure all UI assets or illustrations follow your brand palette perfectly without manual adjustment.

Retro Styling

Recreate the look of classic game consoles or old hardware by using their specific hardware-limited color palettes.

How to Apply Your Custom Palette

  1. 1 Upload Images: Select or drop your PNG, JPG, or WebP files into the upload area.
  2. 2 Define Palette: Enter your desired colors in the text area, one per line (e.g., #FF0000 or "blue").
  3. 3 Configure Options: Enable grayscale conversion if you want to map from gray tones, and choose your export format.
  4. 4 Batch Download: Download individual images or get everything at once in a convenient ZIP archive.

Frequently Asked Questions

What color formats are supported?

You can use Hex codes (#FFFFFF), RGB values (rgb(255,255,255)), or standard CSS color names (white, blue, red).

How does the remapping work?

The tool uses the Euclidean distance algorithm to find the mathematically closest color in your palette for every pixel in the source image.

Is there a limit to the palette size?

While there is no hard limit, we recommend palettes between 2 and 256 colors for the best performance and visual clarity.
