  Here's one I whipped up just now.

 '$INCLUDE: ''
 DIM regs AS regtype
 CLS : LOCATE 10, 10: COLOR 3, 4
 PRINT "A"; : LOCATE 10, 10: COLOR 7, 0
 'get the attribute at the current cursor position
 regs.AX = &H800                           'load function into ah
 regs.BX = 0                               'page number 0
 interrupt &H10, regs, regs
 attribute% = (regs.AX AND &HFF00) \ 256  'attribute is in ah
 IF attribute% AND 128 THEN blink$ = "ON" ELSE blink$ = "OFF"
 background% = (attribute% AND 112) \ 16  'background is bits 4, 5 and 6.
 foreground% = attribute% AND 15          'foreground is bits 0 thru 3.
 character% = regs.AX AND &HFF            'this also returns the character
 'The foreground and background color values are the same as for QB COLOR
 FOR x% = 0 TO background%
  READ background$
 NEXT x%
 FOR x% = 0 TO foreground%
  READ foreground$
 NEXT x%
 PRINT "Foreground = "; foreground$
 PRINT "Background = "; background$

 DATA "black","blue","green","cyan","red","magenta","brown","light gray"
 DATA "dark gray","light blue","light green","light cyan","light red"
 DATA "light magenta", "yellow", "white"
