I'm missing something. Do you mean html color palettes?

An html color is represented either as a hex value of 00->FF for three base color colors:
where 00 is absence of that color and FF is max brightness of that color, e.g.,
black: 000000 or rgb(00,00,00), red: ff0000 rgb(FF, 00, 00)

Usually palletes are displayed with way fewer elements, and they are presented as a sort matrix.

You need an array of 16 million to handle every color, which is not usually a practical approach.

That said what are you trying to do? Exactly? As a guess: Are looking for SDL perl apps?
Simple DirectMedia Layer google for SDL glue.

       Prima::Image::TransparencyControl - standard dialog for transparent color index selection.

DESCRIPTION

       The module contains two classes - "Prima::Image::BasicTransparencyDialog" and "Prima::Image::TransparencyControl". The former provides a
       dialog, used by image codec-specific save options dialogs to select a transparent color index when saving an image to a file.
       "Prima::Image::TransparencyControl" is a widget class that displays the image palette and allow color rather than index selection.

Prima::Image::TransparencyControl

       index INTEGER
	   Selects the palette index.

       image IMAGE
	   Selects image which palette is displayed, and the color index can be selected from.

   Events
       Change
	   Triggered when the user changes "index" property.

Prima::Image::BasicTransparencyDialog
   Methods
       transparent BOOLEAN
	   If 1, the transparent selection widgets are enabled, and the user can select the palette index. If 0, the widgets are disabled; the
	   image file is saved with no transparent color index.

	   The property can be toggled interactively by a checkbox.
