The test cases that i need to work on have a check on the background color of the mainframe screens (I am using RUMBA 7.4), the current methods that i knew Object.bgcolor or getroproperty("bgColor") all are throwing me exceptions,

Is it possible to know whether, I can get the background color and the text color from a mainframe screen?

I am using QTP 9.5 with Terminal Emulator addin.
