When designing a set of keycaps with different colors, why would you ever make the |\ key and the ~` key the same color as the modifiers and special keys like shift, return, ctrl, etc? They're not special keys and theyr'e not modifiers. They belong to the same category as keys which, you know, type characters -- so they should be the same color as the letters and numbers.
I didn't notice, but just got my Eve set in the mail and realize whoever designed it made a kind of stupid, arbitrary decision to color those keys wrong. Bummer.
