SET COLOR ({*; }object; color)
| Parameter | Type | Description | |
| * |  | If specified, Object is an Object Name (String) | |
| If omitted, Object is a Field or a Variable | |||
| object | Field or variable | | Object Name (if * is specified), or |
| Field or Variable (if * is omitted) | |||
| color | Number | | New colors for the object |
Description
The command SET COLOR sets the foreground and background colors of the form objects specified by object.
If you specify the optional * parameter, you indicate an object name (a string) in object. If you omit the optional * parameter, you indicate a field or a variable in object. In this case, you specify a field or variable reference (field or variable objects only) instead of a string. For more information about object names, see the section Object Properties.
The color parameter specifies both foreground and background colors. The color is calculated as:
Color:=–(Foreground+(256 * Background))
where foreground and background are color numbers (from 0 to 255) within the color palette.
Color is always a negative number. For example, if the foreground color is to be 20 and the background color is to be 10, then color is – (20 + (256 * 10)) or –2580.
Note: You can see the color palette in the Form Editor's Object Properties window.
The numbers of the commonly used colors are provided by the following predefined constants:
| Constant | Type | Value |
| White | Long Integer | 0 |
| Yellow | Long Integer | 1 |
| Orange | Long Integer | 2 |
| Red | Long Integer | 3 |
| Purple | Long Integer | 4 |
| Dark Blue | Long Integer | 5 |
| Blue | Long Integer | 6 |
| Light Blue | Long Integer | 7 |
| Green | Long Integer | 8 |
| Dark Green | Long Integer | 9 |
| Dark Brown | Long Integer | 10 |
| Dark Grey | Long Integer | 11 |
| Light Grey | Long Integer | 12 |
| Brown | Long Integer | 13 |
| Grey | Long Integer | 14 |
| Black | Long Integer | 15 |
Note: While SET COLOR works with indexed colors within the default 4D color palette, version 6 introduces the command SET RGB COLORS, which allows you to work with any RGB color.
Example
The following example sets the color for a button named bInfo. The color is set to the values of the two variables named vForeground and vBackground:
SET COLOR (bInfo; – (vForeground + (256 * vBackground)))
