Only a black binder?

While most people use the standard 10" black binder to compete with, it is not a rule! I know it's the norm for a reason; black is non-flashy and because everyone matches no needless attention is drawn to the binder you hold.

But are there people out there who use a different type of binder? Have any of you deliberately chosen a different color for effect or does your district just use its own color? I wonder how that would go, using a new color for the spectacle and impact...any ideas? I think you would lose points.
