Created attachment 91360 [details]
illustrates the color changes after reopening the file

I attributed a new color gradient to an object in Draw. The color gradient is saved in the list as 'kleurovergang 10' (I am using the Dutch version).

When saving the Draw file and reopening it later the gradient color changed to the default blue of LibreOffice.

In the file attached you can see what happens. You see a drawing of a printer with a blue rectangle at the top left. What I intended is a color gradient with yellow pastel. I applied this color gradient to the bottom left printer drawing. But after saving, closing and reopening the file the rectangle turns blue like the top one. 

I included a screen snapshot in the file just before closing the file. There you see the yellow pastel at the bottom.

I noticed when reopening that a new gradient was created with name 'gradient 10' containing the original libreoffice blue. Perhaps the cause is to be looked at the localisation (as gradient is the english for kleurovergang).
