Wingraf COLB

I’m trying to control the background color of the text in my plots.
As per the Wingraf manual, section 3.14 colorcode 1000 is either black or white (how does that make sense?) and 10000 is white. But when I choose colorcode 10000, my background color is purple. How do I make it white?

Please see my example code below:

+prog aqua urs:48.1

end

Hello,

I am not sure why the background colour of the text is purple and not white.
But you can try the number 0000 this should delete the background colour -> white background.

Unfortunately, no background color is not the same as white background. I need the white background as the text is often indistinguishable from the diagram behind it.
