colorize: adapt default style for light backgrounds

The current default theme is unusable on light backgrounds. Some colors
are too light and are almost invisible.

Use only palette colors to ensure that everything is customizable by the
user.

I tested this with white on black, grey on dark purple, black on yellow,
black on white. Text remains readable everywhere.

Update stylesets that don't use these new defaults to explicitly
override them.

Changelog-changed: The default `colorize` theme has been changed to
 use the base terminal colors.
