Bug ID: 153808
Summary: Preview in the Bullets and Numbering is not painting
bullets/numbers in dark mode
Product: LibreOffice
Version: 7.6.0.0 alpha0+ Master
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Impress

Screenshot showing the problem
In Impress, if you open the Bullets and Numbering dialog when using a dark
mode, you'll get a preview without bullets and numbers. See attached screenshot
for more details.
The reason is here:
https://opengrok.libreoffice.org/xref/core/cui/source/tabpages/numpages.cxx?r=71001798#2194
Notice that the color used as background of the output device is
GetFieldColor(), which in a dark theme is a dark color. Later in lcl_DrawBullet
we use this color to determine the bullet color:
aBulletColor = pVDev->GetFillColor().IsDark() ? COL_WHITE : COL_BLACK;
But since pDev is using a dark FieldColor, then COL_WHITE will be used over a
white background in the preview.
Since this is a preview of the document, we should instead use DOCCOLOR and
FONTCOLOR from svtools/colorcfg.hxx
