Hello! Thanks for the fine project
However I met difficulty - I can't change color of cleaning of a background when rendering.

I review "Tutorial2" example.
Following documentation, I replace the setRenderTargetsDefault() function with the following code:

rt = device.getDefaultRTView() #Render target
rt.clearRenderTarget((1.0, 1.0, 1.0, 1.0))
ds = device.getDefaultDSView() #Depth stencil
ds.clearDepthStencil()
device.setRenderTargets([rt], ds)
#Must be released.
ds.release()
rt.release()

get an error APPCRASH: "python.exe program work is stopped", Fault Module Name: d3d11.pyd. No errors in the console and DebugView.

It is checked on two personal computers:
Windows 7, RADEON HD 6670, Python 2.7.5
Windows 7, Intel GMA 945, Python 2.7.2

How do I replace the color?
