Communications pieces for the College of Food, Agricultural, and Environmental Sciences will adopt the signature colors for the university: scarlet, gray, white, and black, as described at http://brand.osu.edu/color/.
Secondary color palettes are also available. Initially these were assigned to a mission area, but now you may choose from any of the palettes. Do keep in mind that colors from each palette are meant to work together. Do not mix colors from one palette with another but feel free to experiment with tints and shades, as shown on the tabs below.
Secondary colors mean just that – scarlet, gray, white and black are the primary colors and should be dominant.
In two-color publications for 4-H, the 4-H clover green may be used in place of one of Ohio State's primary or secondary palettes. A little 4-H green goes a long way; use it as an accent color with black as the primary color.
