Racemenu colors, how to find them?

[Wolfstorm]

I'm making wigs for my characters, as I use them as followers to one another, and need the wigs for when they change their hairs. But I ran into a problem. 

When I apply their hair colors to the hair texture (I'm following the Skywigs tutorial), usually the color is described by six digits In GIMP. This is the standard in any image manipulation software. 

But in Racemenu pick color selection, there are eight digits, not six. The first two digits are related to a value called A. 

What is this value and how do I find it in GIMP? Because I can't match the exact color from the player character for the wig (that will be used by the npc version). It always end up desaturated.

You are looking at the alpha channel (transparency).

OK you talking about changing the hair color of a wig, first it only works for the player not the NPC, second I think you need to update the nodes, if you do itr problematically in game 

You also do not need textures, apply it using nifskope, from memory.. straight to the wig for the default color (not 100% here, and no not checking an old mod)

colors are express's has Hex values  6 characters or 8 characters with an alpha channel  or has RGB 0-255 for each with, the alpha channel being a percentage 

Plus I seem to recall RaceMenu uses both a Hex Value,  and RGB value, open your eyes, you look but you do not see

HINT click on the diamond that is the color 

BTW if the code to change wig color  in game is too hard make different colors wigs, then NPC can use them too

PS I cannot believe you are using a guide and I did that 2014 Notice I never mentioned GIMP, you do not need it.. PLUS I also briefly touch on changing the color in game, but only for the player

Hex color #AB15GF NO alpha channel

Hex color #AB15GFFF with alpha channel

an alpha channel (transparency) is optional in all formats 

RBG

RGB (255, 88, 91) No alpha

with Alpha

RGB (255, 88, 91 / 32% ) 

Edit I can use nifskope, I think I have proved that before, but I have no business writing a tutorial, I am a coder..  I know I will make a mistake

In GIMP try adding an alpha  channel, and tweak it, then tell me it got SIX
