Description:
If you create a relationship between two tables, then delete the relationship the column (FK) still exists.

How to repeat:
1.Create a table called tab1. Give it two columns, one PK with auto_increment column.

2.Create another table called tab2. Give one column, a PK with auto_increment.

3.Create a 1-1 relationship from tab2 to tab1. 
  This will give tab2 a FK.

4.Click on the relationship.

5.Go to Edit>, Then Delete>. 
  
The line will disappear for the relationship, but the column and the colors still exist. I have attached an image located here>>> http://i19.tinypic.com/8g8ujus.png

In the image the tables that were related are:

1 to 2
4 to 3
6 to 5

Suggested fix:
Remove the column that was created. 
Remove the color grouping.
