Color Swatch Lab

Color Swatch Lab is an app for working with colors and palettes.

You can pick a color with your phone camera, choose it from a photo or enter it manually. The app shows the color value in different formats and lets you copy it in one tap.

You can also create color harmonies, generate lighter and darker shades, compare two colors and check whether text has enough contrast against a background.

If you work with photos, Color Swatch Lab can extract a palette from an image. You can choose how many colors you want and save the result as a palette for later.

Your palettes can be edited, reordered and exported as PNG, JPEG, SVG, PDF, TXT, JSON or CSS.

Main features:

• Color scanner using the camera

Camera colors can look slightly different depending on lighting and your phone camera. CMYK values are approximate.
