ColorfulX

ColorfulX is an implementation using Metal for crafting multi-colored gradients.

Special Thanks

The code here is significantly reused from this source, thus the name of original author was added to license file.

The primary focus of this repository is to extend support across multiple platforms, offering a range of ready-to-use presets.

Platform

UIKit and AppKit platforms are generally supported. Due to MTKView not available on visionOS, it’s not supported.

platforms: [
    .iOS(.v14),
    .macOS(.v14),
    .macCatalyst(.v14),
    .tvOS(.v15),
]

Usage

Add this package into your project.

dependencies: [
    .package(url: "https://github.com/Lakr233/ColorfulX")
]

SwiftUI

For animated colors with default animation, use the following code:

ColorfulX(
    colors: ColorSet, // 3 colors are required
    speedFactor: Float = 1,
    bias: Float = 0.001,
    noise: Float = 128,
    power: Float = 8,
    colorInterpolation: MulticolorGradient.ColorInterpolation = .hsb
)

For creating a static gradient, use the following code:

MulticolorGradient(
    points: [ColorStop],
    bias: Float = 0.001,
    power: Float = 2.0,
    noise: Float = 2.0,
    colorInterpolation: ColorInterpolation = .rgb
)

Personally, I prefer to use hsb as color interpolation as it’s more natural to human eyes.

Presets

ColorfulX include a range of presets for you to use. You can identify each in the demo app.
