Hi Matt,
you may create a plot using graphic primitives.
E.g. assume you have your data as 4-tupel, where the first element gives 
the state of the point, e.g. 0 and 1:

dat={{0, 0, 0, 0}, {1, 1, 1, 1}, {0, 0, 0, 1}, {1, 1, 0, 0}}

  We can now use the first element to generate the wanted color:

    { If[#[[1]]==0, Hue[0.5],Hue[1]], Point[Rest[#]]}& /@ dat
], Axes -> True]
