SUMMARY

My desktop environment is GNOME and using the dark themes "Adwaita-dark". I
found that, the results of the function "preview R markdown" can't read. It is
because the themes "Adwaita-dark" forces all the background to black. However,
the default font color of the preview also in black. 

Are there any ways to configure the font color of the "preview R markdown" ?

Thanks.
