Letbe a set of multicolored points in the plane such that no three points are collinear and each color appears on at mostpoints. We show the existence of a non-crossing properly colored geometric perfect matching on(ifis even), and the existence of a non-crossing properly colored geometric spanning tree with maximum degree at moston. Moreover, we show the existence of a non-crossing properly colored geometric perfect matching in the plane lattice. In order to prove these our results, we propose an useful lemma that gives a good partition of a sequence of multicolored points.
