Shade Shaker

Make a color palette, see it in a real app, and copy the code. Shade Shaker is a palette maker for people who build apps and websites.

Press Space for a new palette. Lock the colors you like and keep pressing until the rest fit. Click a color to change it, drag to reorder, and pick a harmony when you want one. Palettes hold up to 10 colors.

See it in an app
Preview shows your palette on real mobile and web screens: a home screen, a details page, settings, a dashboard and a landing page, in light and dark. Choose which colors play primary, secondary, tertiary and background, and the screens follow.

Copy the code
Get a theme ready to paste for Flutter, HTML and CSS, Tailwind CSS, React, Vue, Angular, React Native, SwiftUI, Jetpack Compose, .NET XAML, Python (Matplotlib) or design tokens. For Flutter, the code you copy is the same code that draws the preview, so what you see is what you get.

More tools
- Explore: an endless feed of palettes. Search with words like pastel, warm or ocean, or with a hex value.
- From Image: drop in a photo and pull out its colors. Drag the pickers to fine-tune them.
- Contrast: check text and background colors against WCAG, and fix a weak pair with one click.
- Colors: 5,000 named colors, with their values in HEX, RGB, HSL, LAB, OKLCH and more, plus shades, tints and harmonies.
- Scales: turn colors into full 50-950 scales.
- Gradients: linear, radial and sweep gradients, or even steps between two colors.
