Color & Palette Utility Tools
Every palette, no matter how beautiful, has to be applied: converted, measured, tested, and exported. These utility tools are the workbench underneath all the curated palettes on PocketSwiss — the pickers, converters, checkers, and generators that turn a good scheme into a finished product.
From the essential Color Picker to the Image Palette Extractor, each tool runs entirely in your browser. Nothing is uploaded, nothing is tracked.

Interactive tool — open to useWhy Color & Utility Tools Colors Work
Utility tools save the real time of design: converting between hex, RGB, and HSL; checking contrast against WCAG; naming colors for documentation; and building tint/shade ramps from a single seed.
They also feed each other. Extract a palette from an image, measure it with the picker, adjust with the saturation tool, verify with the contrast checker, and export the result — all without leaving PocketSwiss.
How to Use These Palettes
- Use the Color Picker to sample any color on screen and copy its hex instantly.
- Turn an inspiration image into a working palette with the Image Palette Extractor.
- Verify every text/background pair with the Contrast Checker before shipping.
- Generate a full tone ramp with the Tint & Shade Generator and finish with the Random Palette for surprise ideas.
Frequently Asked Questions
What is the difference between hex, RGB, and HSL?
Hex and RGB are both ways to write the same red-green-blue values; HSL describes the same color by hue, saturation, and lightness, which is easier for humans to reason about.
How do I check if colors are accessible together?
Use the Contrast Checker to measure the luminance ratio between two colors. For normal text, aim for at least 4.5:1; for large text, 3:1.
How do I extract a palette from an image?
Use the Image Palette Extractor — it analyzes the dominant colors in any image you load in the browser and returns a ready-to-use palette with hex codes.
