Rules for the General Use of the 4-H Name and Emblem
The four-leaf clover with stem and the letter "H" in white or gold on each leaflet may also appear, if necessary, in other colors and still be considered the official 4-H emblem. For example, when it is not possible to use the color green for the emblem, as in printing on fabric, plaques, and trophies, other colors may be used.
When used, the 4-H Club name and emblem shall be given a position of prominence. It is not permissible to superimpose any letter, design, or object on the 4-H emblem or to alter its shape in audiovisuals, on stationery over which a letter is written or typed, certificates, publications, etc.
Any use of the 4-H Club name and emblem is forbidden if it exploits the 4-H program, its volunteer leaders, or 4-H youth participants or the United States Department of Agriculture, Cooperative Extension Services of the Land-Grant Universities, or their employees. Also, the 4-H Club name and emblem cannot be used to imply endorsement of commercial firms, products, or services.
