12c forms SMART BAR showing black and white ICONS

Imranswork

Dear All,

I have installed weblogic, forms and reports 12c on windows 2016 server.

The form and reports are working fine. The only issue is that SMART BAR that contains "save", "print", "exit", "enter query" and so on is showing icons in black and white color only.

I need to know how can I make the SMART BAR (default bar) button icons colorful.

Regards,
