I dont' know much about the the Qliview Server, hence apologise for wrongly framing my initial question.
I did a bit of searching around and found that I need to change the color setting for the application in Qlikview AccessPoint.
I believe some .css file in this location needs to edited. "C:\Program Files\QlikView\Server\QvClients\"
Could anyone help with changing the color setting for the Combo Charts in that .css file for qlikview accesspoint?
