[vtk-developers] Interest in a vtkColor class?

[David Cole]

Just one more suggestion regarding the color topic:

Consider supporting "Recognized color keyword names" (Section 4.2 of 
http://www.w3.org/TR/SVG/types.html) as a base set of "pre-defined" 
colors. Alternatively, perhaps there's some other already defined 
standard that might be more appropriate in VTK's case. Remarkably, the 
"named colors" found in Microsoft's .NET framework 
System.Drawing.Colors, the KnownColor enumeration, appear to be derived 
largely from the SVG named colors... Or perhaps it's just coincidence 
that the lists both begin with AliceBlue, AntiqueWhite, Aqua and 
Aquamarine... :-)
