Description
From the docstring for point2d, the following works fine:
sage: p = point(((0.5, 0.5), (1, 2), (0.5, 0.9), (-1,-1)), rgbcolor=hue(1), pointsize=30); p.show()
However
sage: p = point(((0.5, 0.5), (1, 2), (0.5, 0.9)), rgbcolor=hue(1), pointsize=30); p.show()
gives one purple(?) point and two blue points. This seems to happen if and only if the number of points specified is exactly three, regardless of the specified color.

I wonder if this is related to the apparent special casing of 3 or fewer points in GraphicPrimitiveFactory_from_point_list (code below, from sage/plot/plot.py). That was the best lead I can find with the time I have, hope it helps.
