Hi, R_G_B system works only with Color chooser plugin which comes with OpenJUMP Plus. Perhaps that plugin could be modified to give random fills for the selected polygons.
Here comes another idea. Sometimes it would be nice to have polygon maps where adjacent polygons have different colors according to the four color theorem. Or seven colors it that would be easier to compute. That feature would also suit well as an option for Color chooser plugin. http://en.wikipedia.org/wiki/Four_color_theorem<http://en.wikipedia.org/wiki/Four_color_theorem.> http://people.math.gatech.edu/~thomas/FC/fourcolor.html http://146.163.152.131/teaching/projects/poettker_final.pdf -Jukka Rahkonen- ________________________________ Michaël Michaud wrote: Hi, I need to change the color of the selected data.
