look and feel of WAD report in Portal

Hi All

I am very much new to WAD and i am working on developing custom reports in WAD and publishing in portal

i have achieved my functionality, but i am unable to change the look and feel, here is my requirement.

I've put a query into a WAD and I've published the WAD as an ivew. But i want the look and feel to be "Corporate" and not use the SAP standard blues etc. like ia m using a chart item it shld be sap blue in the background, i want my own colors to be used.

please guide me on this i did a bit of R&D but couldnt get exact way out.

Regards
