This element for reed shows a classic plant, painted a classic color. Reeds were year signs in the Mesoamerican calendar and day signs in the day count (tonalpohualli). Reeds also had many practical uses, one of which was for making darts and arrows. Thus, some of the attestations of the glyph for acatl) will look a lot like darts and arrows (acatl or mitl), with their red and yellow coloration and added feathers, but without the arrowhead.
Wikipedia has published a photo of acatl plants.
