Needs["Graphics`Colors`"] (* not needed as of 5.1 *)

pnts = {{1, 2}, {5, 4}, {3, 2}, {2, 6}, {5, 3}};
cnd = {7, 3, 5, 8, 3};

coloredPoints = {If[#2 == 3,
   Blue, Green], Point@#1} & @@@ Transpose@{pnts, cnd};
Show[Graphics@{AbsolutePointSize[7], coloredPoints}, Frame -> True];

or

coloredPoints = Transpose@{
     cnd /. {3 -> Blue, x_Integer -> Green}, Point /@ pnts};
Show[Graphics@{AbsolutePointSize[7], coloredPoints}, Frame -> True]
