仪表盘颜色怎么修改？
Hi @fly257
It's not possible to change the background color of a dashboard. You would have to create a custom build of Metabase.
when you click the top right-hand corner button 
to enter fullsceen mode, you can set up the dashboad to night-mode 
, then the background of the dashboad will become black instead of default white.
Thanks for this solution!
