Qt application display wrong color

bao
Hi,

I am writing a Qt application which has a GUI. The application works OK on
the micro 2440 with 7 inch LCD. But when I run it on the mini2440 with 3.5
inch LCD, it seems like the color is wrong. The main form has a "slight"
blue color. The text edit is yellow, while it is suppose to be white. Did
anyone has this problem before, and how can I fix it?

Thank you very much
