This theme is the ``consequent'' version of |beetle| and uses white/black/gray throughout. It does not go particularly well with themes that use shadows.
+ The theme is based on the the colors of the Monarch butterfly.

Like the |dove| color theme, this theme is useful for printing on a black-and-white printer. However, it uses different shades of gray extensively, which may or may not look good on a transparency.
