+
+The InfiniApps Color Picker, known as InfColorPicker, is a view controller 
+for use in iOS applications to allow the selection of a color from RGB space, 
+but using an HSB representation of that color space to make selection of a 
+color easier for a human.
+
+InfColorPicker is distributed with an MIT license. It supports iPhone OS 3.x 
+as well as iOS 4 and 5.
+
+Usage
+-----
+
+The main component is the `InfColorPickerController` class, which can be 
+instantiated and hosted in a few different ways, such as in a popover view 
+controller for the iPad, pushed onto a navigation controller navigation 
+stack, or presented modally on an iPhone.
+
+The initial color can be set via the property `sourceColor`, which will be 
+shown alongside the user-selected `resultColor` color, and these can be 
+accessed and changed while the color picker is visible.
+
+In order to receive the selected color(s) back from the controller, you have 
+to have an object that implements one of the methods in the 
+`InfColorPickerControllerDelegate` protocol.
+
+Example
+-------
+
+	- (IBAction) changeBackgroundColor
+	{
+		InfColorPickerController* picker = [InfColorPickerController colorPickerViewController];
+		
+		picker.sourceColor = self.view.backgroundColor;
+		picker.delegate = self;
+		
+		[picker presentModallyOverViewController: self];
+	}
+
+	- (void) colorPickerControllerDidFinish: (InfColorPickerController*) picker
+	{
+		self.view.backgroundColor = picker.resultColor;
+		
+		[self dismissModalViewControllerAnimated: YES];
+	}

+The InfinitApps Color Picker, known as InfColorPicker, is a view controller for use in iOS applications to allow the selection of a color from RGB space, but using an HSB representation of that color space to make selection of a color easier for a human.
+
+![InfColorPicker Screenshot](http://f.cl.ly/items/0b0X0Z1t2A170E0c3L1R/InfColorPicker.png)
+
+InfColorPicker is distributed with an MIT license.
+
+It is ARC-based and supports iPhone OS 5 and later (with one small change it could be made compatible back to iOS 4 if that's necessary).
+
+Usage
+-----
+
+The main component is the `InfColorPickerController` class, which can be instantiated and hosted in a few different ways, such as in a popover view controller for the iPad, pushed onto a navigation controller navigation stack, or presented modally on an iPhone.
+
+The initial color can be set via the property `sourceColor`, which will be shown alongside the user-selected `resultColor` color, and these can be accessed and changed while the color picker is visible.
+
+In order to receive the selected color(s) back from the controller, you have to have an object that implements one of the methods in the `InfColorPickerControllerDelegate` protocol.
+
+Example
+-------
+
+	- (void) changeColor
+	{
+		InfColorPickerController* picker = [ InfColorPickerController colorPickerViewController ];
+		
+		picker.sourceColor = self.color;
+		picker.delegate = self;
+		
+		[ picker presentModallyOverViewController: self ];
+	}
+
+	- (void) colorPickerControllerDidFinish: (InfColorPickerController*) picker
+	{
+		self.color = picker.resultColor;
+		
+		[ self dismissModalViewControllerAnimated: YES ];
+	}
+

+
+The InfiniApps Color Picker, known as InfColorPicker, is a view controller 
+for use in iOS applications to allow the selection of a color from RGB space, 
+but using an HSB representation of that color space to make selection of a 
+color easier for a human.
+
+InfColorPicker is distributed with an MIT license. It supports iPhone OS 3.x 
+as well as iOS 4 and 5.
+
+Usage
+-----
+
+The main component is the `InfColorPickerController` class, which can be 
+instantiated and hosted in a few different ways, such as in a popover view 
+controller for the iPad, pushed onto a navigation controller navigation 
+stack, or presented modally on an iPhone.
+
+The initial color can be set via the property `sourceColor`, which will be 
+shown alongside the user-selected `resultColor` color, and these can be 
+accessed and changed while the color picker is visible.
+
+In order to receive the selected color(s) back from the controller, you have 
+to have an object that implements one of the methods in the 
+`InfColorPickerControllerDelegate` protocol.
+
+Example
+-------
+
+	- (IBAction) changeBackgroundColor
+	{
+		InfColorPickerController* picker = [InfColorPickerController colorPickerViewController];
+		
+		picker.sourceColor = self.view.backgroundColor;
+		picker.delegate = self;
+		
+		[picker presentModallyOverViewController: self];
+	}
+
+	- (void) colorPickerControllerDidFinish: (InfColorPickerController*) picker
+	{
+		self.view.backgroundColor = picker.resultColor;
+		
+		[self dismissModalViewControllerAnimated: YES];
+	}
