  Recently, the homology and cohomology of non-k-overlapping discs, or,
equivalently, no k-equal subspaces of Euclidean space, were calculated by
Dobrinskaya and Turchin. We calculate the homology and cohomology of two
classes of more general spaces: decreasing polychromatic configuration spaces
and bicolored configuration spaces. Instead of all points behaving similarly,
we allow for varying behavior between points.
