Changing color of ROI highlight in 'Show All' mode

[ganeshjothikumar]

Hi All
 
       I have an image and I draw a set of ROIs over it and add them to ROI Manager. All this I am doing through a plugin programmatically. Now when I click 'Show All' in the ROI Maneger panel, all the ROIs are highlighted with green color. Is there a way to change this color. I want to change the color in which the ROIs are highlighted when 'Show All' button is pressed in ROI Manager panel. Can anybody help me out in this.
 
Thanks in advance
