The Prof-UIS color selection pop-up menu is an example of how the Prof-UIS standard menu can be extended (see Figure 1).
It features a layout of the matrix of N x M color cells
(see Figure 2,
Figure 3,
Figure 4, and
Figure 5). A more complex layout
(e.g. no cells at certain positions) is also supported.
