How do I reference a cell value and it's background color

I have a cell “Master.B8” and would like to change both the value and the font color of a cell referencing “Master.B8” from another sheet “Panel1.B8”. So if I change the font color on Master.B8 then Panel1.B8 will also change color.

In my opinion, the best solution is to use the same “Conditional Formatting” for each cell. I assume that both cells always contain the same value. A description for the “conditional formatting” can be found here.

With me Windows 10 Home; Version 1809; 64-Bit | LibreOffice, Version: (x64).

Unfortunately Conditional Formatting only tests against values and not styles. Think of the Paste Special command and just paste the format, but in this case that functionality is associated with a =[ref]. So something like =Format(B8;Font_Color) or somesuch.

My only other possible option is to create a basic macro that tests the reference cell for font color then changes the current cell font color. Then make that macro a user function. So something like UserChangeFontColor(B8).

Sorry that my post did not help. But there are enough capable users you can tell you how your desire can be implemented.
