Vista - Translating colors to hex and back

PowerShell/.NET/COM have anything that can take a 'human readable' color
like "red" and convert it to hex, and vice-versa?

42# ipasm System.Drawing # from PSCX 1.1

GAC Version Location
--- ------- --------
True v2.0.50727 C:\WINDOWS\assembly\GAC_MSIL\System.Drawing\2.0.0.0__b...


43# [drawing.Color]::FromName('red')


R : 255
G : 0
B : 0
A : 255
IsKnownColor : True
IsEmpty : False
IsNamedColor : True
IsSystemColor : False
Name : Red

44# "0x{0:X}" -f [drawing.Color]::FromName('red').R
0xFF

To go the other way is a bit harder:

57# [Enum]::GetValues([drawing.KnownColor]) | %{$c = [drawing.color]::FromKnownC
olor($_); if ($c.ToArgb() -eq 0xffff0000) { "The color is $_" }}
The color is Red

Note that the hex format is AARRGGBB where AA is the alpha channel and is normally set to FF.

Ok, but ( curiosity killed the cat ) what is white ?

Thanks VERY much.

BTW: where is this format documented?

The calling seqence is a bit off, I sort of expected
"{0:x} in hex`n{1} in decimal" -f $c.ToArgb() $c.ToArgb()

To work. But it generated an error, whereas:

I was sort of surprised to find this worked:
PSH [D:\foo]: "{0:x} in hex`n{1} in decimal" -f $c.ToArgb(),$c.ToArgb()
ffff0000 in hex
-65536 in decimal

I expected the paramaters to the right of '-f' to be space, not comma
delimited.

Yeah I've been bit by that before. I just had to wire it into my memory
that -f expects an array arguments.
