I am also restoring my Fast Draw and I had some trouble with color matching.
studying some nos playfields , and original flyers I understand that original colors were very different than the colors on my sample after more than 40 years of environmental damage. So I decided to repaint all the colors , given also the fact that the playfield had some serious (bare wood ) damage.
Using createx opaque colors I found that the large light bluish area is almost identical with the createx opaque sky blue (it can be tweaked with maybe 10 sky blue and 1 white) , the darker blues can be produced by mixing 4 blue 3 white , red is 1 red 1 yellow , yellow as is , and all yellowed whites must be painted pure white. All colors from the createx opaque line.

will hopefully be posting some documentation really soon.
