This app shows 50 shades of gray (“grey” if you’re English). The shades are numbered, which makes them even more interesting for Dull Men.
After you’ve viewed the shades on the screen titled “50 Shades” (the second screen of the app), you can take the app’s poll by clicking on the button that says “Poll” in the upper right corner of that screen.
The poll asks users to indicate their favorite shades, both for standalone gray and two-tone gray.
