Hello this Sunday, July 8, 2012 .
I 'm LIBRE OFFICE 3.5.4.2 . By Display > Toolbars> Customize then click the Customize window , Toolbars tab , Color choice , I see the contents of this toolbar . I have not found a way to make it visible in Display > Toolbars . I even tried to create a new toolbar Color2 that is visible in Display … but I can not fill .
GREETINGS . ( I write in French with translation and Lingoes )
Some toolbars open automatically depending on the context.
Do you mean this toolbar (Color toolbar, part of the Picture toolbar)?
Select a graphic object, and you can dock the Color toolbar at the top or bottom; or use it as a floating toolbar.
