-In CUE.NET a brush is used to apply colors to a _KeyGroup_.

 > The whole software-design of CUE.NET is built around brushes so you should use them for every coloring you do.  
 
-CUE.NET provides by the default four gradients:
+CUE.NET provides by default five (+1 deprecated) brushes:
 * [Solid-Color-Brush](https://github.com/DarthAffe/CUE.NET/wiki/Solid-Color-Brush)
 * [Linear-Gradient-Brush](https://github.com/DarthAffe/CUE.NET/wiki/Linear-Gradient-Brush)
 * [Radial-Gradient-Brush](https://github.com/DarthAffe/CUE.NET/wiki/Radial-Gradient-Brush)
 * [Random-Color-Brush](https://github.com/DarthAffe/CUE.NET/wiki/Random-Color-Brush)
+* [Image-Brush](https://github.com/DarthAffe/CUE.NET/wiki/Image-Brush)
+* Profile-Brush (deprecated - only works with CUE 1)
 
 Of course you can always implement [your own brush](https://github.com/DarthAffe/CUE.NET/wiki/Implementing-an-own-brush).
 
 ### Using brushes
-Currently there are two ways of using brushes:  
+Using a brush is straight forward. Just take a _LedGroup_ (remember that the device itself is a _LedGroup_ too) and assign your brush to the _Brush_-Property. 
 
-* Directly apply the brush to any _KeyGroup_ you like (including the keyboard itself). This can be done simply by setting the _Brush_-Property.  
 ```C#
 IBrush brush = new SolidColorBrush(Color.White);
-keygroup.Brush = brush;
+myLedGroup.Brush = brush;
 ```
 
-* As part of an [effect](https://github.com/DarthAffe/CUE.NET/wiki/Understanding-CUE.NET-effects).

+> In most cases it's recommended to use the device-brush as an background and work on a ledgroups only, even if you want to color the whole device. Otherwise using transparency might cause some sort of color-bleeding.
+> Adding a rainbow over the whole keyboard could look like this:
+> ```C#
+CueSDK.KeyboardSDK.Brush = (SolidColorBrush) Color.Black;
+ILedGroup rainbowLeds = new ListLedGroup(CueSDK.KeyboardSDK, CueSDK.KeyboardSDK);
+rainbowLeds.Brush = new LinearGradientBrush(new RainbowGradient());
+CueSDK.KeyboardSDK.Update();
+>```
+
+### Configuring brushes
+Every brush offers a basic set of options to customize it's look.   
+* **BrushCalculationMode**   
+There are two values for this: _Relative_ (which is the default) and _Absolute_. They affect how the brush is render on the keyboard.   
+_Relative_ will cause the whole brush to be rendered inside the smallest rectangle which contains all LEDs of the ledgroup this brush is assigned.   
+_Absolute_ causes the brush to be rendered over the whole device but only colors the LEDs of by the ledgroup.   
+An example would be a ledgroup containing the left half of a keyboard. Applying a rainbow in _Relative_-mode will start with red on the left side and stop with red at the center of the keyboard. Using _Absolute_ it will start on the left side with red too, but will stop with cyan at the center (only the left half of the rainbow is drawn).
+   
+* **Brightness**   
+This property affects the overall brightness of the brush in percent (0f-1f).
+   
+* **Opacity**   
+This property affects the overall opacity of the brush in percent (0f-1f).
+   
+* **ColorCorrections**   
+This property offers a list of [Color-Corrections](https://github.com/DarthAffe/CUE.NET/wiki/Color-Corrections) to modify the colors rendered by the brush.
