### Name

> XmHTMLAllocColor - a convenience function for allocating a color

### Synopsis

> Pixel XmHTMLAllocColor(Widget w, String color, Pixel def_pixel)

### Description

> XmHTMLAllocColor allocates the requested color using the colormap of the given widget. When the color can not be matched exactly, a least squares algorithm is used to search for the closest color in the colormap.

> w
>   Specifies the parent Widget ID. Colors are allocated using the colormap of this widget, which does not have to be a XmHTML widget;
> color
>   Specifies the color to be allocated. This can be either a symbolic name (e.i., `SlateBlue`) or an RGB triplet of the form #RRGGBB. Case is ignored;
> def_pixel
>   the pixel to be returned if the requested color could not be allocated;

### Return Value

> A pixel value representing the allocated color.

### Examples

> Allocate the (symbolic) color red and return the default black pixel if allocation fails.

    	Pixel pix;
    	Widget w;
    	pix = XmHTMLAllocColor(w, "Red", BlackPixelOfScreen(XtScreen(w)));

> Allocate a RGB color and return the default white pixel if allocation fails.

    	Pixel pix;
    	Widget w;
    	pix = XmHTMLAllocColor(w, "#3e0fc1", WhitePixelOfScreen(XtScreen(w)));
