Only way I know of is to rectangle select each (square/rectangle) then fill with the colour you want. Or make your own grid over the one that is there.
That grid is not seen in the picture. Like guides are not 'seen' in the end result.
There may be a way, I'll keep looking. OK I found out how you can do it.
I tried from the edit menu and the fill with bucket is greyed out. You need to go to the tools menu up the top and click on bucket fill from there. Make sure the + sign is what is over the square you want filled.
Does it if you select the bucket fill from the toolbox too. You just have to be careful to use the + as your marker

You need to use the bucket fill tool.
BUT ➤ it mandatory to adjust things in the Tool Options
you have to select Fill by line art detection and adjust other settings like Fill transparent area if your grid is on a transparent layers,
Select if the grid is above the current layer, the layer itself, etc...
Also you have to do some tests with the last 3 sliders (growing/detection threshold/ max gap) to fine tune the "line art" detection and the growing over the grid or not.
Once you're set, it's piece of cake



Last but not least you can let the window Change Foreground Color open, while changing color, it will apply live, so no need to hit the button OK, and then re-open that window, just change the color ➤ bucket fill ➤ change the color ➤ bucket fill, and so on

You can change it here
