[GIS] Multi-Colored Polygon in Thematic Map

arcmapthematic map

I have to make a thematic map with an attribute table with duplicated features but different attributes. See below:

FEATURE   ATTRIBUTE
-------------------
1         bl
1         gr
2         gr
2         re
3         re
4         bl
5         ye
5         ye

Does anyone knows how to paint a feature (polygon) with the corresponding colors? I mean like for feature 1 paint half blue and half green, for feature 2 half green half red… Thanks.

You have a couple billion possible color combinations... I guess hash symbols are out of the question! I think that I would use pie charts.
If you add 16 new attributes to your table and name each field for a color. Then you can give each attribute a value of 1 if the feature should have that color. When you set up your pie chart, you need to make sure that the symbol for the "Red" attribute is indeed red, etc.
Now when you add the pie charts if there is a "1" value in both the "Blue" and "Green" your pie chart will be 50/50 Blue and Green... If you have a "1" value in all 16 color attributes, you will get a beautiful rainbow pizza with even slices.
