Pragmatic color utilities for SwiftUI and UIKit.

ColorKit helps you parse hex colors, check accessibility contrast, generate palettes, build gradients, and simulate color‑vision deficiencies — all with a tiny, focused API that feels at home in Swift.

Add the package to Xcode or your Package.swift using the public repo and a tag.

• URL: https://github.com/ckdash-git/ColorKit.git
• Minimum platforms: iOS 13+, macOS 12+, tvOS 13+, watchOS 6+

// Package.swift
.dependencies: [
    .package(url: "https://github.com/ckdash-git/ColorKit.git", from: "0.1.1")
]
.targets: [
    .target(
        name: "App",
        dependencies: [
            .product(name: "ColorKit", package: "ColorKit")
        ]
    )
]

In Xcode: File → Add Packages… → paste the URL → add the ColorKit product.

Add to your Podfile (iOS example):

platform :ios, '13.0'
use_frameworks!

target 'App' do
  pod 'ColorsKit', '~> 0.1'
end

Then run pod install and import the module:

import ColorKit

Note: The CocoaPods pod name is ColorsKit, but the Swift module is ColorKit.

• Hex parsing to and from RGBA (#RGB, #RGBA, #RRGGBB, #RRGGBBAA)
• WCAG contrast ratio and AA/AAA compliance checks
• Palette generation around a base color
• SwiftUI/UIColor helpers (dynamic light/dark, gradients)
• Color‑blindness simulation (protanopia, deuteranopia, tritanopia)

import ColorKit

// Hex → RGBA
let fg = try HexColorFormatter.parse("#1A73E8")
let bg = try HexColorFormatter.parse("#FFFFFF")

// Contrast ratio + WCAG
let ratio = ColorMath.contrastRatio(fg, bg)
let isAA = Accessibility.meets(.AA, foreground: fg, background: bg)
let isAAA = Accessibility.meets(.AAA, foreground: fg, background: bg)

// Palette around a base color
let palette = PaletteGenerator.generate(from: "#1A73E8", steps: 6, range: 0.25)

// Simulate color‑vision deficiency
let protanopia = ColorBlindnessSimulator.simulate(.protanopia, rgba: fg)

import SwiftUI
import ColorKit

// Create Color from hex
let primary = Color(hex: "#0A84FF")

// Dynamic light/dark Color (bridges via UIKit on iOS)
let dynamic = Color.dynamic(lightHex: "#FFFFFF", darkHex: "#000000")

// LinearGradient from hex list
let gradient = SwiftUIGradientBuilder.linear(hexColors: ["#0A84FF", "#5E5CE6"]) 

import UIKit
import ColorKit

let primary = UIColor(hex: "#0A84FF")
let dynamic = UIColor.dynamic(lightHex: "#FFFFFF", darkHex: "#000000")

A tiny command‑line demo lives in Example/ConsumerSample/.

• Run: cd Example/ConsumerSample && swift run
• Shows: hex parsing, contrast ratio, palette generation, and color‑blindness simulation.

• ColorCore: RGBA, HexColorFormatter, ColorMath, Accessibility, Theme, ThemeManager
• ColorUtilities: PaletteGenerator, AccessibilityUtils, ColorBlindnessSimulator
• ColorExtensions: SwiftUI/UIColor helpers, gradients
• ColorPalettes: Predefined themes and palette helpers

• Color.dynamic bridges to Color(uiColor:) on iOS/tvOS.
• On iOS/tvOS < 15, Color.dynamic falls back to the light variant.
• CocoaPods support: iOS and macOS in 0.1.0; tvOS/watchOS coming in a follow‑up release.

This repo follows semantic versioning. Start with 0.1.0 and evolve via tags.
