This is the help entry called "colors" from FPW2.6 help. At the bottom it
seems to cover which colour pair numbers affect what part of various
objects. I think the section "User defined windows (Scheme 1)" is what
applies to you.
Sorry, I've lost the text formatting, I tried to paste as HTML or something
but no joy.
Hope this helps.

FoxPro offers a sophisticated set of commands for full control of colors.
By default, FoxPro for Windows and FoxPro for Macintosh take their colors
from the Control Panel settings. The Control Panel colors are mapped to the
FoxPro color schemes. The colors can be overwritten using the FoxPro SET
COLOR commands described in this section.
In FoxPro for Windows and FoxPro for Macintosh, you can set colors directly
with the SET COLOR commands or interactively in the Control Panel. Refer to
your Windows or Macintosh documentation for more information about setting
colors with the Control Panel.
In FoxPro for MS-DOS, you can define the colors of elements of the FoxPro
system interface (the system menu bar, windows, alerts, dialogs, and so on)
and user-defined objects (controls, menus, windows, and so on). You can set
colors directly with the SET COLOR commands or interactively with the Color
Picker dialog, which is available by choosing Color... from the Window menu.
The Color Picker dialog provides the fastest way to set colors and allows
you to save color sets for later use. See the FoxPro User's Guide for more
information on setting colors with the Color Picker dialog see the "Window
Menu" chapter in the FoxPro for MS-DOSUser's Guide.
Certain commands, like DEFINE WINDOW, support optional COLOR and COLOR
SCHEME clauses that let you specify colors of user-defined objects directly.
We recommend that you let Windows handle all coloring issues. Refer to the
Microsoft Windows manuals for more information on setting colors through the
Color dialog.
If you prefer to set a different default set of colors when FoxPro is
started, you can programmatically create and save your own custom default
color set using the CREATE COLOR SET DEFAULT command. Use this default
color set by specifying it in the FoxPro CONFIG.FPW configuration file.
The following topics contain more information on colors:

Color Schemes

Color Pairs
A color pair consists of a foreground and background color combination.
FoxPro uses eight basic colors: red, green, blue, cyan, magenta, yellow,
white and black. Each color has two intensity levels: low intensity (dark)
and high intensity (bright).
You can specify color pairs using either of two methods:
Character color codes
RGB color codes
Each method is described in detail below.
Character Code Color
FoxPro for MS-DOS uses character abbreviations (R, G, B, W, N) for color
values. Each color can have an attribute to change the intensity level.
Color codes that contain the plus sign (+) denote a bright foreground.
Similarly, color codes that contain the asterisk (*) denote a bright
background.
The plus sign (+) and the asterisk (*) can be placed anywhere in the color
pair.
Character Code Example
The following example shows the character color code for red on dark gray
(high intensity black):
R+/N
You could also use any of the following to specify the same color code:
+R/N
R/N+
R/+N
Remember that both signs (+,*) denote high intensity (or brightness). The
plus sign (+) denotes foreground intensity, and the asterisk (*) denotes
background intensity no matter where they are located in the expression.
FoxPro for Windows supports the character codes for color. These codes,
however, are internally converted to the RGB system when program code is
generated and compiled.
RGB Color Pairs
You can also specify colors the RGB color values. These values range from 0
(lowest intensity or no color) to 255 (high intensity or bright color).
Each foreground and background requires three values, one for red, one for
green, and one for blue. A color pair, therefore, requires six values,
three for the foreground and three for the background.
RGB Example
The following example shows the RGB color code for red on dark gray (high
intensity black):
RGB(255,0,0,128,128,128)
The first three values in the RGB expression above set the foreground color
to red and the second three values set the background color to dark gray
(see the table below).
FoxPro uses a different color representation for the Windows version than it
does for the MS-DOS version. Both FoxPro for MS-DOS and FoxPro for Windows
accept the RGB and character color codes. Each of the color representations
are described in sections that follow.
The following is a table of the colors that are available in FoxPro for
MS-DOS, including the character codes and the corresponding RGB codes for
FoxPro for Windows.
Color RGB Foreground Background
White 255,255,255 W+ W*
Black 0,0,0 N N
Gray 192,192,192 W W
Dark Gray 128,128,128 N+ N*
Red 255,0,0 R+ R*
Dark Red 128,0,0 R R
Yellow 255,255,0 GR+ GR*
Dark Yellow 128,128,0 GR GR
Green 0,255,0 G+ G*
Dark Green 0,128,0 G G
Cyan 0,255,255 BG+ BG*
Dark Cyan 0,128,128 BG BG
Blue 0,0,255 B+ B*
Dark Blue 0,0,128 B B
Magenta 255,0,255 RB+ RB*
Dark Magenta 128,0,128 RB RB
Blank N/A X X
When you use custom colors, the following rules apply for converting RGB
values into character codes:
When ALL of the three color values (R, G or B) are below 32, the character
code is N.
When ALL of the three color values (R, G or B) are between 32 and 64, the
character code is N+.
When ALL of the three color values (R, G or B) are between 65 and 191, the
character code is W.
When ANY of the three color values (R, G or B) are above 191 the character
code is high intensity (+ or *).
Examples
R G B Character
100 80 175 W
100 200 175 W+/*
33 56 45 N+/*
33 56 175 B
33 56 245 B+/*
100 100 3 GR
Color Pair List
A color pair list consists of one to ten color pairs separated by commas. A
color scheme is composed of ten color pairs. For example, W+/B, W+/BG,
GR+/B, GR+/B, R+/B, W+/GR, GR+/RB, N+/N, GR+/B, R+/B. A monochrome color
pair list might look like W/N, N+/W, W+/N, W+/N, W/N, U+/N, W+/N, -, W+/N,
W/N.
Color Schemes
A color scheme is a set of ten color pairs. Each color pair in a color pair
list corresponds to an item in a color scheme. The color pair list for a
color scheme can be returned with SCHEME( ) or RGBSCHEME( ).
A user-defined object (GET, check box, list, push button) takes on the color
scheme of the window it is drawn in. A user-defined menu takes on the
colors of scheme 2. You can override the default scheme of a user defined
object by including the color scheme clause with the command. The following
commands support the color scheme clause:
@ ... EDIT - Text Edit Regions
@ ... FILL
@ ... GET
@ ... GET - Check boxes
@ ... GET - Invisible buttons
@ ... GET - Lists
@ ... GET - Popups
@ ... GET - Push Buttons
@ ... GET - Radio Buttons
@ ... SAY
@ ... TO
BROWSE
CHANGE
DEFINE BAR
DEFINE MENU
DEFINE PAD
DEFINE POPUP
DEFINE WINDOW
EDIT
SHOW GET
SHOW OBJECT
Color Set
A color set consists of 24 color schemes. The complete color environment
can be saved in a color set. Color sets, like keyboard macros and memory
variables, can be saved for later use. A color set can be assigned a name
of up to ten characters and saved. Color sets are stored in the FOXUSER.DBF
resource file. You can load a color set with SET COLOR SET.
Commands and functions you can use to manipulate color schemes include:
RGBSCHEME( ) Function
SCHEME( ) Function
SET COLOR OF SCHEME Command
SET COLOR SET Command

On monochrome monitors, only four "colors" are available: white (W), black
(N), underlined (U) and inverse video (I).
An asterisk (*) can be added to make the background color bright. A plus
sign (+) denotes high intensity for the foreground color.
Color pairs can also be specified with a set of 6 RGB (Red Green Blue) color
values separated by commas. The first three color values specify the
foreground color and the second three color values specify the background
color. The color values can range from 0 through 255.
For example, the color pair R/W can also be specified with this RGB color
pair:
RGB(255,0,0,255,255,255)
In FoxPro for Windows, you can set colors directly with the SET COLOR
commands or interactively in the Windows Control Panel. For more
information about colors in FoxPro for Windows, see Colors.
