After examining the files shared by you, I have come to know that the first file is MSP 2013 and it doesn’t use shades. The seconda MPP file is in MSP 2013 and there are no shades used. Aspose.Tasks has SaveOptions.UseGradientBrush property for rendering colors in shades. Could you please elaborate your requirements with respect to shades a little more so that we can look into these in detail and assist you further?
