Chalco (Mdz3v)
This is a colorful painting of the simplex glyph for the place name Chalco ("In the Hollow," according to Gordon Whittaker). It is also the sign for chalchihuitl (local jade), with its mottled green center (the stone), with a red ring and other concentric rings suggesting resplendence.

The red ring around the green stone may also suggest a metaphorical passage to an interior, like a shore around a body of water. Mirrors, also circled in red, might have been considered in a similar way. The green stone seems to serve as a phonetic indicator for the term chal, hollow.
