See Suisai in action

Suisai's tools are designed to work together. See how they fit into everyday creative work, from collecting colors throughout the day to building palettes, testing accessibility, and using the results in your designs or code.

Explore eight real workflows, each with a short video demonstration.

• Capture what catches your eye

  Inspiration can come from anywhere, and the colors you notice are worth keeping.

• Find colors in photographs

  Find the colors in an image, refine your selections and save them as a reusable palette.

• Build your own palettes

  Build a palette from scratch with whichever color controls suit you, or from colors you have already saved.

• Explore color relationships

  Fill the shades between two colors, or work out what sits alongside one, and keep whatever you find.

• Compare and mix colors

  Explore color differences, experiment with spectral mixing and create entirely new combinations.

• Check color accessibility

  Test contrast, find accessible alternatives and evaluate color combinations across an entire palette.

• Work with the palettes you already have

  Index the palette files you already keep, wherever they sit, and read the colors out of your stylesheets too.

• Take your colors wherever you need them

  Drag them into your design tools, your editor, or the system color picker, and export whole palettes in the format your project wants.

Privacy isn't an optional feature.

Far too many applications and services track what we do, including software we've already paid for. I find that completely unacceptable. Buying an application shouldn't mean surrendering information about how you use it, what you're working on, or where you go online.

That's why I built Suisai differently. I don't need to know which colors you sample, what images you open, or which applications you use. None of that is my business.

Suisai has no analytics, tracking, advertising, or user accounts. Your images and palettes are processed locally, without being uploaded to a server. The direct-download version makes limited requests to check for updates, handled by a separate sandboxed helper. The App Store version relies on Apple's update system.

If you want to tell me how Suisai has helped your work, suggest an improvement, or report a problem, I'd genuinely love to hear from you. But that's your information to offer, not mine to collect.

One palette. Many destinations.

Your colors shouldn't have to be recreated for every application or project. Suisai generates ready-to-use color values and complete palette exports, whether you're working with stylesheets, application code, or design tools.

The examples below show a five-color palette exported as CSS, followed by a single color formatted for several different development environments. No manual conversion or retyping required.

Name your colors yourself, or choose automatically from 31,914 named colors matched using OKLab. Suisai prepares color names for use as code identifiers and lets you select the CMYK profile used for conversion in Settings, so your output will use the same color profile as your print workflow.
