Color renderer not working......

Question

Hello...
I am displaying color in a table column... But instead of showing the color it is printing the color object like java.awt.Color[r=122,g=134,b=167]. What could be wrong....
I am using AbstractTableModel and using fireTableRowsInserted and Updated method to add row to the table. I table row is a string of Objects. Please help... I am running out of time. I have a demo of my work as soon as I am done, so help please . I am adding the code below.
Object[] dataRecord = new Object[5];
dataRecord[0] = (Object)instStateClr;
dataRecord[1] = InstId;
dataRecord[2] = StartTime;
dataRecord[3] = EndTime;
dataRecord[4] = CorrValue;
instactTabModel.updateInstActSumm(dataRecord);
This is a string of Object of which the first location contains a color object.
The color renderer used is as follows...
instActyTable.setDefaultRenderer(Color.class,
new ColorRenderer(true));
The abstract table model is as given below...
