Background Color of Dialog: #FFFFFF

Inner Border Color Around Dialog :#FF9900 #FF9900 #FF9900 #FF9900

Outer Border Color Around Dialog:#FF9900 #FF9900 #FF9900 #FF9900

Border Color of Title Area:#0000CC

I can see color changed in Theme Editor but same not coming while logging in portal and checked.

Every thing is fine except Background Color of Title Area this color not applying .
