PRB: SET COLOR TO Results in Differing Shades of Gray

ID: Q114791

The information in this article applies to:

Microsoft FoxPro for Macintosh, versions 2.5b, 2.5c
Microsoft Visual FoxPro for Macintosh, version 3.0b

SYMPTOMS

The default desktop color is a different shade of gray than the default color pair displayed for scheme 1 in FoxPro for Macintosh.

CAUSE

This behavior occurs because the default color set is actually using an RGB value for the color information. The color pair listing returned by scheme(1) returns information in color pair letters, which are an approximation of the current RGB settings. The SET COLOR TO n/w* command uses a different set of RGB values to represent gray.

RESOLUTION

To restore the default desktop color programmatically, issue the following commands:

   SET COLOR TO
   CLEAR

For more precise control over the colors, use RGB values instead of color pairs.

MORE INFORMATION

Steps to Reproduce Behavior

1. Start FoxPro for Macintosh.

2. Issue the following commands in the Command window:

      SET COLOR TO
      CLEAR
      ?SCHEME(1)

   Note that the desktop is a pale gray. The first color pair listed for
   scheme 1 is "N/W*".

3. Issue the following commands in the Command window:

      SET COLOR OF SCHEME 1 TO "n/w*"
      CLEAR
      ?SCHEME(1)

Note that the desktop is now a darker shade of gray, although the color pair information returned by the second ?SCHEME(1) command is identical to the color pair information returned by the first command.
