Subject: [vtkusers] How to color 2 sides of a plane by different colors?<br>

I have seen these example : VTK/Examples/Cxx/PolyData/Colo<wbr>rCellsWithRGB<br>

<<a href="https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.vtk.org%2FWiki%2FVTK%2FExamples%2FCxx%2FPolyData%2FColorCellsWithRGB&data=02%7C01%7Classo%40queensu.ca%7C4e4e1233eed14fb7582908d5350e830e%7Cd61ecb3b38b142d582c4efb2838b925c%7C1%7C0%7C636473258804797130&sdata=zV1gDfw%2BnadYhcDfyeEGzYQjZXS1em8zKq%2FL7ELYYu4%3D&reserved=0" rel="noreferrer" target="_blank">https://www.vtk.org/Wiki/VTK/<wbr>Examples/Cxx/PolyData/ColorCel<wbr>lsWithRGB</a>><br>

<br>

and I understand how to color different cells.<br>

But is it possible to color 2 sides of the plane in different colors?<br>

<br>
