How to change Background Text color in WB Options using scripting?

One can use SetPreferenceValue() to change the text colour. One can paste the below scripts in WB Scripting console.

To change the colour to white:
SetPreferenceValue('GraphicsTextColor','0 0 0 0')

To change it back to black:
SetPreferenceValue('GraphicsTextColor','255 255 255 255')
