A totally white Pa Kua Mirror?

I want to hang a Pa Kua mirror above my attached garage door to reflect the poison arrow coming from an oncoming street. All of the Pa Kua which I have seen online mirrors are brightly colored which would make them quite the obvious and odd looking eye-sore. Does a Pa Kua have to be brightly colored? I have seen nothing written explaining the colors required and the ones I see online seem to be all very different color schemes. Can I make one with white paint and slightly off white tri-grams so that it blends in with the white colored siding of the home?
