This is a lightweight Android library that provides Jetpack Compose @Composable UI to select colors. This open as a bottom sheet in default. But developers can use individual peaces available in the library as per their requirements.

• Color Picker BottomSheet
• Pick color from RGB-A values
• Pick color from Predefined color grid
• Pick color from HSL-A values (Color spectrum)

To show case all features and functionalities of this library, there is a reference app we build. Application is already available in Google Play Store. Reference app code is available in GitHub.

Add following in your root build.gradle/build.gradle.kts at the end of repositories:

dependencyResolutionManagement {	repositories {	mavenCentral()	maven { url 'https://jitpack.io' } // jitpack.io repository configured.	} } 

Add the following dependency to your build.gradle / build.gradle.kts file: For Groovy - build.gradle:

dependencies { implementation 'com.github.KvColorPalette:KvColorPicker-Android:2.2.0' } 

For Kotlin DSL - build.gradle.kts:

dependencies { implementation("com.github.KvColorPalette:KvColorPicker-Android:2.2.0") } 

After you integrated the KvColorPicker-Android library, you can consume it as follows.

As a main functionality, consumer can use color picker bottom sheet in there application as follows.

// Create state variable to show and hide bottom sheet val showSheet = remember { mutableStateOf(false) } val sheetState = rememberModalBottomSheetState(skipPartiallyExpanded = true) // Button click to open bottom-sheet Button( onClick = { sheetState.value = true } ) { Text("Open Color Picker") } // Color Picker bottom sheet UI if (showSheet.value) { KvColorPickerBottomSheet( showSheet = showSheet, sheetState = sheetState, onColorSelected = { selectedColor -> // Do anything when you have selected color } ) } 

RGB-A Picker	GRID Picker	HSL-A Picker

Developer can add the each color picker (RGB-A Picker, Grid Picker and HSL-A Picker) separately in their own UI. Because KvColorPicker-Android provided.

RGBAColorPicker( modifier = Modifier, onColorSelected = { selectedColor -> // Action with selected color } ) 

GridColorPicker( modifier = Modifier, onColorSelected = { selectedColor -> // Action with selected color } ) 

HSLAColorPicker( modifier = Modifier, onColorSelected = { selectedColor -> // Action with selected color } )
