BSP portal display problem (Urgent!!!)

Hi Friends,

I am new to BSP. I am trying to change the customer logo and sap logo on my bsp portal page, but doing that I have converted my IC_BASE.CSS file to BSP by right clicking it.

Now I am facing problem that the color display is not coming properly on the portal, can some one tell me how to revert the color scheme back?

Regards,

Abhishek..
