Most people say their favorite color is blue (although it's not our most popular color for binders and boxes). Maybe it's because blue is all around us in both the sky and the ocean. Some shades of blue generate a sense of calming or indicate loyalty, while others can appear cold and off-puting. It's often related to wisdom and loyalty. A blue binder or box might indicate your loyalty to somebody close, but may not be an ideal gift for someone you wish to know better.
