filling polygon with white

when i try to fill a polygon with white, it fills with black and prints in black. how do i fill with white?

 

Go to View>Option and choose the Appearance tab. At the bottom you'll see Invert
Pen and Invert Pattern. Check both tick boxes.

FYI, it can be a good idea to change your drawing screen to tan or grey or some
other soft color. Easier on the eyes, and you'll see the white fill. Do this
globally in Windows: r-click on the Desktop default screen, choose Properties and
look at the Appearance tab there. You'll see how to do it.
