Color question

[kadil <ksadil bigpond net au>]

I have an appthat is reading data from an odbc database and drawing the 
results on a drawing area. One line drawn per row returned. Table data as 
follows:

Start_of_line   End_Of_Line     Color
0                       10                      565466
10                      17                      99094
17                      42                      255 

One of the columns returned is a color. So I want to draw the each rectangle 
colored as per the record. When I try to change the color, it changes the 
color of all the previous rectangles that I have drawn. Do I need to define a 
separate color for each possible color option?

Thanks,
Kim
