[vtk-developers] Interest in a vtkColor class?

[Mathieu Malaterre]

Andrew,

	Basically what you are asking is to include by default:

	VTK/Common/Testing/Cxx/vtkTestingColors.h

	The solution of the hash seems a bit too elaborate since the colors are 
not supposed to change. So I would rather see a solution like 
vtkTestingColors.h.

My 2 cents,
Mathieu
