i've seen it change colors when it really should not when i edit the Column Width in Manage Views - i know its strange, but how about adjusting that Column Width size and see if it corrects it for you?
I don't sure Column Width is same object size. but i set object size is 32x32 (default).
and some time when i restart all service Solarwind object will show correct color.
now i update service pack 2 for Orion 9 object show correct color.
i don't sure if i restart service again object will show correct color.
