xihuitl (TK224v)
This painted simplex Nahuatl hieroglyph is a year (xihuitl) sign. It is a square tipped so that one corner is down, almost like a diamond shape. The square has a golden border, and inside the border is a mosaic of tesserae of what may be different shades of turquoise: yellow, blue, and green. Turquoise (also xihuitl) is a homonym for year.

Many year signs do have a square shape with a border, but they can also be round.
Side Note: The folio numbers are not always clear in the copy published online by the British Museum. Marc Thouvenot gives this page the number K22_B in his TLACHIA digital collection, https://tlachia.iib.unam.mx/tepetlaoztoc/K22_B
