Spectrum is an Android library that makes it easy to let your user pick from a list of colors.

Download with Gradle:

implementation 'com.alexeypertcev:spectrum:0.7.1-fork'
implementation 'org.greenrobot:eventbus:3.0.0'

The library is hosted on both Bintray (JCenter) and Maven Central; use whichever you prefer.

repositories {
  jcenter()
}

• SpectrumDialog with Builder pattern
• SpectrumPreference for easily adding color selection to your app's preferences
  • Can be added either in XML or programatically
• SpectrumPreferenceCompat for use with the preference support library
• SpectrumPalette for integrating a color selection view into any part of your app

First, make sure the project's information is configured correctly in the ext block in spectrum/build.gradle. Next, put your Bintray information in your local.properties file; you will need to define bintray.user, bintray.apikey, and bintray.gpg.password.

To deploy the artifacts, run the following commands. The first is a dry run to make sure the artifacts can be built correctly. The second actually deploys to Bintray.

./gradlew install
./gradlew bintray
