Take a look at SystemWindow class>>#open:label:, which sends
#openInWorld to the newly created system window.
SystemWindow>>#openInWorld sends #widgetsColor:
to itself, before sending #openInWorld to super.
SystemWindow>>#widgetsColor: sends #adoptWidgetsColor:
to self, which recurses through the morph hierarchy
to set all widgets' colors to the system window's
color. To make things a bit "more complicated"
PluggableButtonMorph overrides #adoptWidgetsColor:
to mix the system window's color with the theme's
button color.
Cuis goes through this complicated rigamarole,
to provide nice colored browser windows,
which are still themeable.

The net effect is:
#color: is honored and than rudely written
over by the system window. I suggest sub-classing
PluggableButtonMorph and overriding #adoptWidgetsColor:
according to your needs and taste.
