An alternative approach (maybe there's a bug on this already?) would be
to ship a pre-defined color palette and when the user goes to select a
color for the tag, present them with the next color from the subset of
unused colors from the palette.

A nice effect of this is that we can provide a set of colors that look
good (e.g. avoiding dark colors, or shades that will be
indistinguishable).

The palette should be loadable. This would permit users who don't like
our choice of colors to select another. E.g., one palette could provide
vibrant primary colors, another one focuses on more subtle pastels, etc.
This also would permit distros to provide a palette that fits with their
distro default color scheme if they desire.

The one problem I had with this idea was that a palette would have a
finite set of colors. However, using Izidor's idea might solve that -
once # tags > # colors-in-palette, generate new colors by selecting ones
in between.
