How to solve color problem in draft analysis?

while doing draft analysis i am getting the result in mix of colors(Blue+green).Generally we should get green color in cavity and blur color for core and red color if any undercut.
Is there any graphics problem in my system or i need to do some settings in Catia?
Please help to solve the problem and i have installed Catia V5 R20.
Thanks in advance !
