I am using controlP5 to control a window containing a 3D scene of spheres.  I am using a seperate control window, which I created using the sample code by Andreas Schegel as follows.  After implementing the control window in my processing program, the colours in my 3D scene are changed and the colours that I used for my spheres using the fill() call no longer correspond to what they were originally.  Spheres that were cream coloured appear to have a reddish tint to them.  It should be noted that when I set the background to cream eveything is fine.  It appears as though fill is not working the same as before.  Any suggests would be greatly appreciated.

 

 * ControlP5 Controlframe
* with controlP5 2.0 all java.awt dependencies have been removed
* as a consequence the option to display controllers in a separate
* window had to be removed as well.
* this example shows you how to create a java.awt.frame and use controlP5
