Palette

public final class Palette
extends Object

java.lang.Object
   ↳ androidx.palette.graphics.Palette


A helper class to extract prominent colors from an image.

A number of colors with different profiles are extracted from the image:

  • Vibrant
  • Vibrant Dark
  • Vibrant Light
  • Muted
  • Muted Dark
  • Muted Light
These can be retrieved from the appropriate getter method.

Instances are created with a Palette.Builder which supports several options to tweak the generated Palette. See that class' documentation for more information.

Generation should always be completed on a background thread, ideally the one in which you load your image on. Palette.Builder supports both synchronous and asynchronous generation:

 // Synchronous
 Palette p = Palette.from(bitmap).generate();

 // Asynchronous
 Palette.from(bitmap).generate(new PaletteAsyncListener() {
     public void onGenerated(Palette p) {
         // Use generated instance
     }
 });
