You can use the PaletteSource property to specify the palette for a form or report. Read/write String.
expression.PaletteSource
expression Required. An expression that returns one of the objects in the Applies To list.
Enter the path and file name of one of the following file types:
The default setting is (Default), which specifies the palette included with Microsoft Access. If you change this setting by entering a path and file name, the property setting displays (Custom).
You can set this property by using the form's or report's property sheet, a macro, or Visual Basic.
For a form, you can set the PaletteSource property in form Design view and Form view. The property setting is unavailable in other views.
For a report, you can set the PaletteSource property only in report Design view. The property setting is unavailable in other views.
Windows can have only one color palette active at a time. Microsoft Access allows you to have multiple graphics on a form, each using a different color palette. The PaletteSource and PaintPalette properties let you specify which color palette a form uses when displaying graphics.
When you set the PaletteSource property for a form or report, Microsoft Access automatically updates its PaintPalette property. Conversely, when you set a form's or report's PaintPalette property, the PaletteSource property is also updated. For example, when you specify a custom palette with the PaintPalette property, the PaletteSource property setting changes to (Custom). The PaintPalette property (which is available only in a macro or Visual Basic) is used to set the palette for the form or report. The PaletteSource property gives you a way to set the palette for the form or report in the property sheet by using an existing graphics file.
