Color Palette The requirement of color should be spelled out as much as possible; use hex codes, equivalent CMYK or Pantone color values to be used for print — whatever you choose to go with, ensure they are tested in print first. This is important to avoid any discrepancies between what is found online and what appears in print. Iconography or Other Imagery Iconography can really help your brand stand out in the crowd. Have the specification for it in your guide so they are used properly in all documents. You can spell out the variations it may have in color or filter for different purposes such as the pattern on a report versus the pattern on inside of an envelope. Linking the exact image within the guide would be wise.
