I have looked at the example for the new scan book and am confused.

For example, take ZALR04. This is a white frame. The scan code on it near the top of page 59 has a "D", which mean "Dark" engraving. At the bottom of page 59, it shows ZALR04A and ZALR04B (which has an "L" and "D" respectively). If the frame only comes in white, why is there a "Light" engraving option?

Conversely, ZALR01 has a dark background with an "L". At the bottom of the page, it also has an "L" and "D" option. If the product only comes in a dark background, why is there a "Dark" option?

Hopefully, you can straighten me out.

Thanks,
