# Jetpack Compose Extended Colors
[](https://jitpack.io/#SmartToolFactory/Compose-Extended-Colors)
* Utility library that extends Compose Colors with Material Design2 colors, Color swatches like in
[Flutter](https://api.flutter.dev/flutter/material/Colors-class.html).
* Material Design 3 tonal and Core palettes,
see [Material Design 3 site](https://m3.material.io/styles/color/the-color-system/key-colors-tones)
for more information about the Material 3 color system and tonal palettes.
* Rotatable gradients by 45 degrees with aim to add rotation by any angle in the future
* Functions to convert between `androidx.compose.ui.graphics.Color`, `HSL`, `HSV`, `RGB`, `HCT`, and
colors with **Name** based on distance to pre-defined elements in json in 3D space using `Red`
, `Green`, `Blue` values of picked Color.

## Gradle Setup
To get a Git project into your build:
* Step 1. Add the JitPack repository to your build file Add it in your root build.gradle at the end
of repositories:
```
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
```
* Step 2. Add the dependency
```
dependencies {
implementation 'com.github.SmartToolFactory:Compose-Extended-Colors:'
}
```
## Material Design 2 Colors & Swatches
### Material Colors
[Material Colors](https://materialui.co/colors/) can be accessed from Red to BlueGrey. Brown, Grey, and
BlueGrey swatches only have primary colors.
```kotlin
val Red50 = Color(0xffFFEBEE)
val Red100 = Color(0xffFFCDD2)
val Red200 = Color(0xffEF9A9A)
val Red300 = Color(0xffE57373)
val Red400 = Color(0xffEF5350)
val Red500 = Color(0xffF44336)
val Red600 = Color(0xffE53935)
val Red700 = Color(0xffD32F2F)
val Red800 = Color(0xffC62828)
val Red900 = Color(0xffB71C1C)
// Accent Colors
val RedA100 = Color(0xffFF8A80)
val RedA200 = Color(0xffFF5252)
val RedA400 = Color(0xffFF1744)
val RedA700 = Color(0xffD50000)
```
### Material Swatches
Call any swatch from `ColorSwatch` for instance for Red500 with `ColorSwatch.red` which will return
primary color `Map`
```kotlin
val red by lazy {
linkedMapOf(
50 to Color(0xffFFEBEE),
100 to Color(0xffFFCDD2),
200 to Color(0xffEF9A9A),
300 to Color(0xffE57373),
400 to Color(0xffEF5350),
500 to Color(0xffF44336),
600 to Color(0xffE53935),
700 to Color(0xffD32F2F),
800 to Color(0xffC62828),
900 to Color(0xffB71C1C)
)
}
```
to access any color from this map
```
val redSwatch = ColorSwatch.red
val red300 = redSwatch[300]!!
```
Swatch that returns header(50 variants)
```kotlin
val primaryHeaderColors by lazy {
listOf(
Color(0xffF44336),
Color(0xffE91E63),
Color(0xff9C27B0),
Color(0xff673AB7),
Color(0xff3F51B5),
Color(0xff2196F3),
Color(0xff03A9F4),
Color(0xff00BCD4),
Color(0xff00ACC1),
Color(0xff4CAF50),
Color(0xff8BC34A),
Color(0xffCDDC39),
Color(0xffFFEB3B),
Color(0xffFFC107),
Color(0xffFF9800),
Color(0xffFF5722),
Color(0xff795548),
Color(0xff9E9E9E),
Color(0xff607D8B)
)
}
```
## Material Design 3 Tonal Palette
A tonal palette consists of thirteen tones, including white and black. A tone value of 100 is
equivalent to the idea of light at its maximum and results in white. Every tone value between 0 and
100 expresses the amount of light present in the color.
From range 0 to 100
```kotlin
val material3ToneRange = listOf(
0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 95, 99, 100
)
```
Call that returns list of colors
```kotlin
fun getColorTonesList(color: Color): List {
val camColor = Cam16.fromInt(color.toArgb())
val palette: TonalPalette =
TonalPalette.fromHueAndChroma(camColor.hue, max(48.0, camColor.chroma))
val toneList = mutableListOf()
material3ToneRange.forEach { shade ->
toneList.add(Color(palette.tone(shade)))
}
return toneList
}
```
or to get Map with tone keys
```kotlin
fun getColorTonesMap(color: Color): Map {
val palette: TonalPalette = TonalPalette.fromInt(color.toArgb())
val toneMap = linkedMapOf()
material3ToneRange.forEach { shade ->
toneMap[shade] = Color(palette.tone(shade))
}
return toneMap
}
```
## Gradient Rotation
Gradients can be rotate by 45, in the future this can be expanded to any angle, with
Create a `GradientOffset`with
```kotlin
var gradientOffset by remember {
mutableStateOf(GradientOffset(GradientAngle.CW0))
}
```
```kotlin
fun GradientOffset(angle: GradientAngle = GradientAngle.CW0): GradientOffset {
return when (angle) {
GradientAngle.CW45 -> GradientOffset(
start = Offset.Zero,
end = Offset.Infinite
)
GradientAngle.CW90 -> GradientOffset(
start = Offset.Zero,
end = Offset(0f, Float.POSITIVE_INFINITY)
)
GradientAngle.CW135 -> GradientOffset(
start = Offset(Float.POSITIVE_INFINITY, 0f),
end = Offset(0f, Float.POSITIVE_INFINITY)
)
GradientAngle.CW180 -> GradientOffset(
start = Offset(Float.POSITIVE_INFINITY, 0f),
end = Offset.Zero,
)
GradientAngle.CW225 -> GradientOffset(
start = Offset.Infinite,
end = Offset.Zero
)
GradientAngle.CW270 -> GradientOffset(
start = Offset(0f, Float.POSITIVE_INFINITY),
end = Offset.Zero
)
GradientAngle.CW315 -> GradientOffset(
start = Offset(0f, Float.POSITIVE_INFINITY),
end = Offset(Float.POSITIVE_INFINITY, 0f)
)
else -> GradientOffset(
start = Offset.Zero,
end = Offset(Float.POSITIVE_INFINITY, 0f)
)
}
}
```
Set start and end of `Brush` with
```kotlin
val redGreenGradient = Brush.linearGradient(
colors = listOf(Color.Red, Color.Green, Color.Blue),
start = gradientOffset.start,
end = gradientOffset.end
)
```
## Color Names
Create an instance of `ColorNameParser` with
```kotlin
@Composable
fun rememberColorParser(): ColorNameParser {
return remember {
ColorNameParser()
}
}
```
And call `ColorNameParser.parseColor(color)`
Call it in a launchedEffect with snapshotFlow or in a ViewModel or UseCase
```kotlin
LaunchedEffect(key1 = colorNameParser) {
snapshotFlow { color }
.distinctUntilChanged()
.mapLatest { color: Color ->
colorNameParser.parseColorName(color)
}
.flowOn(Dispatchers.Default)
.collect { name: String ->
colorName = name
}
}
```
## Conversions
You can use `ColorItem` which has functions that enables user to convert from `Color` to
other type
```kotlin
/**
* Data class that wraps [Color] and contains extend information about this color such
* as HSL, HSV, RGB, HEX counterparts.
*/
data class ColorItem(var color: Color) {
val hexARGB
get() = colorToHexAlpha(color)
val hex
get() = colorToHex(color)
val hsvArray
get() = colorToHSV(color)
val hslArray
get() = colorToHSL(color)
val rgb
get() = colorToARGBArray(color)
val alpha:Float
get() = color.alpha
val red: Int
get() = color.red.fractionToRGBRange()
val green: Int
get() = color.green.fractionToRGBRange()
val blue: Int
get() = color.blue.fractionToRGBRange()
var label: String = Unspecified
companion object {
const val Unspecified = "?????"
}
}
```
You can also convert between `Color`, `HSL`, `HSV`, `RGB`, and
colors with utility functions. call color model you want to conveert from, `to` then the
color model you want to convert to
