====================
Changing Plot Colors
====================

This example illustrates use of matplotlib and upsetplot color settings, aside
from matplotlib style sheets, which can control colors as well as grid lines,
fonts and tick display.

Upsetplot provides some color settings:

* ``facecolor``: sets the color for intersection size bars, and for active
  matrix dots. Defaults to white on a dark background, otherwise black.
* ``other_dots_color``: sets the color for other (inactive) dots. Specify as a
  color, or a float specifying opacity relative to facecolor.
* ``shading_color``: sets the color odd rows. Specify as a color, or a float
  specifying opacity relative to facecolor.
