With Mathematica 7.0... First, you don't need to load any package at 
all.  Next, something like

   Histogram[RandomReal[NormalDistribution[0, 1], 100]]

will still give you the default uniform blue.  But the option ChartStyle 
allows you to change this. E.g.,

   Histogram[RandomReal[NormalDistribution[0, 1], 100],
      ChartStyle -> Red]

changes that blue to red.  The option ChartElementFunction allows 
different effects to be applied to the bars, e.g.:

   Histogram[RandomReal[NormalDistribution[0, 1], 100],
      ChartStyle -> Red, ChartElementFunction -> "GlassRectangle"]

See the on-line documentation.
