********************************************
This is for information purposes only.  I had to figure out a bit more about the differences between complete background and foreground controls and this wasn't the total solution I wanted.
The original program shows the problem, and with the examples I couldn't figure how the custom R,G,B settings would be shared with the background..
The Problem
 Code:
  REM SET MODE TO 8 USING VDU (
      VDU 22,8
      REM SET LINE THICKNESS TO 3
      VDU 23,23,3|
      REM OFF
      GCOL 1
      COLOUR 1,175,165,150
      FILL 100,100
      COLOUR 157
      INPUT TAB(0,5) "Enter Your Information  " A$
      PRINTTAB(0,6);A$
      (mou)
      WAIT 0 : REM just wait, nothing to do !
      GOTO (mou)
 
And here is the solution:  Thanks to Richard
 Code:COLOUR 1,175,165,150 : Set palette color 1 to RGB triplet
 COLOUR 128+1 : REM Set text background to palette color 1
 CLS
 INPUT TAB(0,5) "Enter Your Information: " A$
 PRINTTAB(0,6);A$
 
And his other sample given
 Code:
 MODE 8
 COLOUR 1,175,165,150 : Set palette color 1 to RGB triplet
 GCOL 0 : REM Set graphics foreground to palette color 0
 GCOL 128+1 : REM Set graphics background to palette color 1
 VDU 5 : REM Treat text as graphics (transparent background)
 CLG
 MOVE 0,800
 PRINT "Hello world!"
