This is the chemical series description. It recognises input from a limited list, see below. This input is used to set the background color, and is shown in the tooltip for each cell. The word unknown is recognised (showing a grey background), When the category= input is not recognised (not in this list), it will return a black cell.

The input is case-insensitive (A and a accepted).
