1. A computer-implemented method comprising:
generating first data comprising:
a tag including a first plurality of elements, each of the first plurality of elements having a respective color value selected from a set of color values,
a first corner of the tag, the first corner having a first edge and a second edge connecting to define the first corner, and
a first gradient feature, proximate to the first corner, that transitions from a first color value, of the set of color values, to a second color value, of the set of color values, wherein the first gradient feature is external to the tag; and
determining, based on the first data, output data.
