Kroma - Your Color Library

Find a color palette, pick colors from a photo, and copy the values you need for your next design. Kroma brings a color library, photo tools, and color conversion together on iPhone and iPad. EXPLORE COLOR LIBRARIES Browse Chinese and Japanese traditional colors, ready-made palettes, and gradients. Find the closest library colors to a color value you enter. PICK COLORS FROM PHOTOS Extract four colors from a photo, or use the photo picker tool to sample a specific point. Combine sampled colors into a palette to save or share. CONVERT COLOR VALUES Convert between HEX, RGB, HSL, HSV, and OKLCH. Preview the result and copy the format you need. CHECK CONTRAST AND BUILD SHADES Check text and background colors against WCAG AA and AAA contrast thresholds. Create a scale from light to dark while keeping your base color in the middle. KEEP YOUR FAVORITES Save solid colors, palettes, and gradients. Sync favorites across devices with the same iCloud account when iCloud is enabled for Kroma. LEARN AS YOU CREATE Explore short color guides with interactive examples for formats, palettes, and contrast. Questions or feedback: [email protected]
