[Gmsh] Postprocessing high-order fields - strange colors

[Martin Vymazal]

Hello,

  when I open a field stored in gmsh on high-order elements (i.e. at 
least P2) and click on Tools -> Options -> Adapt visualization grid, the 
colors in the plot suddenly become much darker (observed with recent 
builds of gmsh). These colors are then preserved when I save the plot to 
a file (say png). Could you please fix this. Thank you.

Best regards,

  Martin
