Source code


This is a library that provides a Singleton class containing default colors specified in the:

  • Material Color System.
  • Flat Design Color system used in web design.
  • Official colors for several mainstream companies: Google, Twitter, Instagram, YouTube etc.

It provides helper methods for selecting random colors in any of these coloring systems.


Use DesignColors:

  • When you specifically need to work with Material or Flat Design Colors in Kotlin code.
  • When you need to reference design colors mainstream apps for personal purposes.

This is a singleton class and can directly be copied into your project module.

Material Design Colors


To select Material Blue 50:

val blue50 = DesignColors.MaterialDesign.BLUE_50

Then apply it to a View or Widget:

val textView: TextView = findViewById(
textView.background = blue50

To retrieve all Material Blue Colors in an Integer Array:

val blueColors = DesignColors.MaterialDesign.blueColorArray

To choose a random Material Blue Color:

val randomBlueColor = DesignColors.MaterialDesign.randomBlueColor()

To choose a random Material Color:

val randomMaterialColor = DesignColors.MaterialDesign.selectRandomColor()

Flat Design Colors


To select Flat Design Midnight Blue 50:

val midNightBlue50 = DesignColors.FlatDesign.MIDNIGHT_BLUE_50

Then apply it to a View or Widget:

val textView: TextView = findViewById(
textView.background = midNightBlue50

To retrieve all Flat Design Midnight Blue in an Integer Array:

val midnightBlueColors = DesignColors.FlatDesign.midNightBlueColorArray

To choose a random Flat Design Midnight Blue Color:

val randomMidnightBlueColor = DesignColors.FlatDesign.randomMidNightBlueColor()

To choose a random Flat Design Color:

val randomFlatDesignColor = DesignColors.FlatDesign.selectRandomColor()


To choose YouTube Red:

val youtubeRed = DesignColors.YouTube.RED 

To select Snapchat Yellow:

val snapchatYellow = DesignColors.Snapchat.YELLOW

Java Interoperability

Design Colors is completely interoperable in Java.

To select Material Blue 50:

int blue50 = DesignColors.MaterialDesign.getBLUE_50();

To select Flat Design Midnight Blue 50:

int midNightBlue50 = DesignColors.FlatDesign.getMIDNIGHT_BLUE_50();

To select Facebook Messenger's Light Blue:

int midNightBlue50 = DesignColors.Facebook.Messenger.getLIGHT_BLUE();

Using the INSTANCE to access each method and variable for any singleton object is legal however it is a longer syntax.

int midNightBlue50 = DesignColors.Facebook.Messenger.INSTANCE.getLIGHT_BLUE();
