And instead of the black and gold you can use two other colors that provide sharp contrast and legibility (white on navy, for example). The graphic and the text must be the same color.
As for putting it up at "every other teller station" I have seen setups where a conforming sticker was placed on plexiglass that's part of the teller "window" setup, half way between tellers. So that an eight-teller setup would have seven stickers. Personally, I don't think the piddling savings is worth the examiner discussions. Arrange to have the sign posted at each window.
