Actually it is a feature. Patterns are uncoloured now (see PDF
reference for Uncolored tiling patterns) to allow the application of
symbol-color command on patterns.

Now you need to define just the shape of all symbols in Metapost and
color of any symbol in layout, which is much more flexible. It
wouldn't work for patterns consisting of more than one colour, but
nobody has complained so far.

There is some influence of Metapost version, though. Version older
than 1.000 doesn't (easily) support passing the colour information for
patterns so they are all rendered black regardless of symbol-color
setting.
