ColorPicker missing background colors in IDE

  • Platform information:
    • Hardware: Windows x86
    • OS: Win10
    • Java Runtime Environment: 1.8
    • openHAB version:2.4

Which is what I would expect.

Any idea how to get this working in the IDE? I am developing a bainding that needs a colorpicker and it is slow going in part to not knowiing what the color I picked is.
