Hue is the all-in-one coloring utility that you'll ever need.

You can easily use hex colors with theinit(hex:) convenience initializer onUIColor. It supports the following hex formats#ffffff,ffffff,#fff,fff

letwhite=UIColor(hex:"#ffffff")letblack=UIColor(hex:"#000000")letred=UIColor(hex:"#ff0000")letblue=UIColor(hex:"#0000ff")letgreen=UIColor(hex:"#00ff00")letyellow=UIColor(hex:"#ffff00")

letwhite=UIColor(hex:"#ffffff")letblack=UIColor(hex:"#000000")if white.isDarkColor{} // return falseif white.isBlackOrWhite{} // return true

.alpha is a sugar forcolorWithAlphaComponent, internally it does the exact same thing, think of it as alipstick for your implementation.

letcolorWithAlpha= myColor.alpha(0.75)

You can easily create gradient layers using thegradient() method on arrays withUIColor.As an extra bonus, you can also add a transform closure if you want to modify theCAGradientLayer.

letgradient=[UIColor.blackColor(),UIColor.orangeColor()].gradient()letsecondGradient=[UIColor.blackColor(),UIColor.orangeColor()].gradient{ gradientin  gradient.locations=[0.25,1.0]return gradient}

letimage=UIImage(named:"My Image")let(background, primary, secondary, detail)= image.colors()

You can get red, green, blue, and alpha components from any UIColor by using the (red|green|blue|alpha)Component property.

letmyColor=UIColor(hex:"#ffafc2")letmyColorBlueComponent= myColor.blueComponentletmyColorGreenComponent= myColor.greenComponentletmyColorRedComponent= myColor.redComponentletmyColorAlphaComponent= myColor.alphaComponent

letred=UIColor.redColor()letgreen=UIColor.greenColor()letyellow= red.addRGB(green)letdesaturatedBlue=UIColor(hex:"#aaaacc")letsaturatedBlue= desaturatedBlue.addHue(0.0, saturation:1.0, brightness:0.0, alpha:0.0)

This super simple example that displays a bunch of color schemes in a Carousel view.

It uses hex to set the color for the schemes. It leverages from.isDarkColor to make the text color readable in all scenarios.

The demo also featuresSpots for rendering the Carousel view.

Example code:

letcolor=UIColor(hex:"#3b5998")backgroundColor= colorlabel.textColor= color.isDark?UIColor.whiteColor():UIColor.darkGrayColor()

This examples shows how much fun you can have with combiningCAGradientLayer withCABasicAnimation.

It uses.hex for getting the colors and.gradient() for transforminga collection ofUIColor's into aCAGradientLayer.

The demo featuresSpots for rendering the list view andFakery for generating random content strings.

Extract from the demo:

lazyvargradient:CAGradientLayer=[UIColor(hex:"#FD4340"),UIColor(hex:"#CE2BAE")].gradient{ gradientin    gradient.speed=0    gradient.timeOffset=0return gradient}

Hue is available throughCocoaPods. To installit, simply add the following line to your Podfile:

pod'Hue'

Hue is also available throughCarthage.To install just write into your Cartfile:
