I am to make a plot with 200 different colors corresponding to 200 individulas. I want the colors to be as different as possible, because I want to be able to distinguish between the individuals.

I have tried using 

col = alpha(topo.colors(200)[i],0.3)
col = alpha(rainbow(200)[i],0.3)
col = alpha(i,0.3)

where i corresponds to the individuals in a loop. topo.color and rainbow uses different colors, but they are very alike, so it is not possible to see the differences.

    It is impossible to make a graph with 200 colors that are so different that the human eye can grasp it. I strongly advise to find a different approach, e.g. split your graph or group your individuals. – RHA Aug 01 '15 at 08:35
