From the developer:
Create color palettes for all your products and client projects. There are powerful transforms: It can resolve duplicate colors, automatically name your colors, change the formatting of their names or sort them, for example by hue. The app lets you unbox the existing meaning of colors: Importing the colors from a ACO, CSS, Less or Sass file is as simple as dragging and dropping.
