Hi,
The backlight effect will "visually" show as a 2 pixel border around each thumb. I can turn the border to any color. I was using the rose-pink to compliment the green for your logo / Store colors.
The only problem with the narrow green was the box with the models measurements. It squishes too small to be readable. I assume it could be redone. I would also rework the table to use white and grey background and better space arrangement. The green background then serves to anchor those elements. I can rework the table for demo.

Edit: I agree with your last comment. I work the exact pixel measurements first, then I build. I did a rough-layout last night before bed.
