The PALETTEENTRY structure specifies the color and usage of an entry in a logical color palette. A logical palette is defined by a LOGPALETTE structure.

typedef struct tagPALETTEENTRY { // pe
 BYTE peRed;
 BYTE peGreen;
 BYTE peBlue;
 BYTE peFlags;


 peRed Specifies a red intensity value for the palette entry.

 peGreen Specifies a green intensity value for the palette entry.

 peBlue Specifies a blue intensity value for the palette entry.

 peFlags Specifies how the palette entry is to be used.

The peFlags member may be set to NULL or one of the following values:

Value Meaning

PC_EXPLICIT Specifies that the low-order word of the logical palette entry designates a hardware palette index. This flag allows the application to show the contents of the display device palette.

Specifies that the color be placed in an unused entry in the system palette instead of being matched to an existing color in the system palette. If there are no unused entries in the system palette, the color is matched normally. Once this color is in the system palette, colors in other logical palettes can be matched to this color.

Specifies that the logical palette entry be used for palette animation. This flag prevents other windows from matching colors to the palette entry since the color frequently changes. If an unused system-palette entry is available, the color is placed in that entry. Otherwise, the color is not available for animation.
