Reading color of user screen

I am run on redhat 7.3 using screen sections with foreground and background color and would like to know if there is a way to determine if a user screen is showing up properly in color, because if it is not then I want to try for white on gray instead of the stark white and black that happens now. Maybe the lack of expected results is due to terminal type or some other setting but I think I should be able to write a character in say white on blue and then read that character to see if that is the result I expected. Was thinking about the library routine of cbl_read_scr_chattrs but not sure how to compare the information received in the attribute buffer.  Any suggestions?   Snip from current code below where I have had to use the routine for cbl_scr_set_pc_attribute to have screen rewrites work properly.

Thank you.
