Friedrich Huebler <huebler@rocketmail.com> reports that reducing the intensity
of a named color using the <name>*<#> syntax makes that intensity change
"stick" so that the named color is attenuated in all ensuing graphs.

This was a known problem that was reported last week to Stata Technical
Services <tech-support@stata.com>.  The problem was fixed and that fix will be
available in an update scheduled for early next week.

In the interim, rather than shut Stata down, the colors can be reset by typing
either -discard-.
