The colors are not remembered in the section Recent of the "Select the color" dialog called from the sidebar. While you are working with a single object, the Recent section is filled by colors, but as soon as you switch focus out from this object, the Recent section becomes empty again.
Reproduced. 1. Draw a shape 2. Set color to area or line from sidebar 3. Deselect shape 4. Select shape again and check recent colors Changing component to LibreOffice as this affects every component with drawing features.

Yes, it's a well known problem. The recent colors are stored in PaletteManager, which is a member of the button controller. So when the button + anything related are destroyed, we're losing the recent list as well.
In the Alpha version of LibreOffice 5.3.0, the issue seems to be fixed. I see the recent colors remembered among all the color pickers and moreover between different LO components. Also the recent colors are now memorized between LO restarts. Thanks for the fix to everyone involved!
