[[LONG]] [[HEX$|Hexadecimal]] values can be used to set a [[_PALETTECOLOR]] instead of using [[_RGB32]] or [[_RGBA32]] values.


* Hexadecimal digits can  be represented as any number or letter up to F: '''0 1 2 3 4 5 6 7 8 9 A B C D E F'''

* [[_BYTE|Byte]] values up to 255 can represented by two hexadecimal digits such as 1C, 23, FA, etc.

* The [[HEX$|hex]] value for bright white(attribute 15) is &HFFFFFFFF or:

::: [[_ALPHA|Alpha]] = FF (255), Red = FF (255), Green = FF (255), Blue = FF (255)

* [[_RGB]] will return an alpha value of 255 for fully opaque 32 bit colors only. Values range from &HFF000000 to &HFFFFFFFF.

* [[_RGB32]] will return an alpha value of 255 for fully opaque colors only. Values range from &HFF000000 to &HFFFFFFFF.

* [[_RGBA]] can set the transparency so hexadecimal values range from &H000000 (zero alpha) to &HFFFFFFFF (full alpha).

* [[_RGBA32]] can set the transparency so hexadecimal values range from &H000000 (zero alpha) to &HFFFFFFFF (full alpha).


* So expanding on the principle above allows us to easily make up our own hex color values:

:: _PALETTECOLOR 1, '''&HFFFF0000''' 'COLOR 1 is full red
:: _PALETTECOLOR 2, '''&HFFFF00FF''' 'COLOR 2 is purple
:: _PALETTECOLOR 3, '''&HFFFFFF00''' 'COLOR 3 is brown

:Where '''FF''' is the fully opaque [[_ALPHA]] and the 3 hex color values can range from '''00''' to '''FF''' (0 to 255) each.

:''Explanation:'' [[VAL]] is used to convert the [[HEX$|hexadecimal]] [[STRING|string]] values to valid 32 bit color values for [[_PALETTECOLOR]].
:: No VAL conversion is necessary if the [[LONG]] [[&H]] hexadecimal values are entered into the program directly by the programmer.
