Simple Color Palette

View, create, and edit color palettes in the Simple Color Palette format.

The app also provides Quick Look preview and thumbnails for such files.

A color palette is a collection of colors with optional names, essential for designers to maintain consistent branding, create cohesive user interfaces, and share color schemes across projects and teams.

This is the official app for creating palettes in the Simple Color Palette format. It’s intentionally minimal. It’s not a palette organizer or palette generator.

Frequently Asked Questions

I have a feature request, bug report, or some feedback

Click the feedback button in the app or send it here.

Is this a palette organizer app?

No. This app is specifically designed for creating and editing color palettes in the Simple Color Palette format. For organizing collections of palettes, use Finder, your preferred file management app, or a dedicated palette organizer app.

Why doesn’t the app show color values in Hex format?

The app supports extended sRGB colors (wide gamut / HDR) with values outside the 0-255 range. For example, -97 197 261. Hex notation (#ff69b4) is limited to standard RGB values and cannot properly represent extended color values.

Can I export palettes to other formats like ASE (Adobe Swatch Exchange)?

No. The app is focused on the Simple Color Palette format.

What’s the benefit of the Simple Color Palette format over ASE?

The Simple Color Palette format is an open JSON-based format that supports HDR colors and isn’t tied to any specific ecosystem. Unlike ASE, which is a proprietary binary format limited to Adobe products, Simple Color Palette is human-readable, platform-independent, and designed for modern color management needs with support for extended color gamuts.

Can I edit a color?

Yes. Right-click (macOS) or long-tap (iOS) a color to edit.

Can I change the order of colors?

Drag and drop the color to move it to a different position.

Can I copy a color’s value?

Yes. Right-click (macOS) or long-tap (iOS) a color to copy its value.

Can I drag and drop colors between palettes?

Because of a macOS/iOS bug, this is not currently possible.

Can I sync palettes between devices?

Yes. You can save the palettes to iCloud Drive or any file sharing method. The palettes are just files.

How do I import colors from other apps?

You can paste or drop colors from other apps.

Why do the color values shown in the app differ from those in the file?

The app shows display RGB values (gamma-corrected) for easier understanding, while the file stores linear RGB values for technical precision. Both represent exactly the same color, just expressed in different formats.

Does it support OKLCH?

You can copy colors as OKLCH. Adding color in OKLCH format is planned.

What is OKLCH?

Learn more.

Does the app support color spaces other than sRGB?

The Simple Color Palette format stores colors in linear sRGB, which can be converted losslessly to any other RGB color space while supporting extended range values for HDR colors.

How can I make the window always stay on top on macOS?

Click the “Stay on Top” toggle in the “Window” menu.

Can I use the palettes in my own apps?

Yes. The format is open source and has a Swift implementation available.

Can I compare two palettes side by side?

Yes. Just open both palettes.

Does it support gradients?

No, only flat colors are supported.
