Modding Help Opacity in hex code

So I came across something I don't really understand. In the "mughat.head" file, the colors all show "cc" behind the usual hex code, which gave me some issues when I tried to get the colors in paint.net.
When removing the cc, I get the right color as shown in-game. But apparently the cc stands for the opacity of the color, although I have no idea what opacity level is the right one, since paint.net doesn't show any code for this (as far as I'm aware).

Any suggestions on how to find this out? I need it to change the base colors of the image, so that if it's shown in a collection, people will see the default colors and not the copper/orange-ish from the files.

Code:

"colorOptions" : [
    // BEER YELLOW
    { "ffca8a" : "fcf27ecc", "e0975c" : "f1db1ccc", "a85636" : "eeb70fcc", "6f2919" : "a7d9fbcc" },
    // BLACK
    { "ffca8a" : "838383cc", "e0975c" : "555555cc", "a85636" : "383838cc", "6f2919" : "151515cc" },
    // GREY
    { "ffca8a" : "b5b5b5cc", "e0975c" : "808080cc", "a85636" : "555555cc", "6f2919" : "303030cc" },
    // WHITE
    { "ffca8a" : "e6e6e6cc", "e0975c" : "b6b6b6cc", "a85636" : "7b7b7bcc", "6f2919" : "373737cc" },
    // RED
    { "ffca8a" : "f4988ccc", "e0975c" : "d93a3acc", "a85636" : "932625cc", "6f2919" : "601119cc" },
    // ORANGE
    { "ffca8a" : "ffd495cc", "e0975c" : "ea9931cc", "a85636" : "af4e00cc", "6f2919" : "6e2900cc" },
    // YELLOW
    { "ffca8a" : "fcf27ecc", "e0975c" : "f1db1ccc", "a85636" : "eeb70fcc", "6f2919" : "642f00cc" },
    // GREEN
    { "ffca8a" : "b2e89dcc", "e0975c" : "51bd3bcc", "a85636" : "247824cc", "6f2919" : "144216cc" },
    // BLUE
    { "ffca8a" : "96cbe7cc", "e0975c" : "5588d4cc", "a85636" : "344495cc", "6f2919" : "1a1c51cc" },
    // PURPLE
    { "ffca8a" : "d29ce7cc", "e0975c" : "a451c4cc", "a85636" : "6a2284cc", "6f2919" : "320c40cc" },
    // PINK
    { "ffca8a" : "eab3dbcc", "e0975c" : "d35eaecc", "a85636" : "97276dcc", "6f2919" : "59163fcc" },
    // BROWN
    { "ffca8a" : "ccae7ccc", "e0975c" : "a47844cc", "a85636" : "754c23cc", "6f2919" : "472b13cc" }
  ]

 

If you want no transparency, the code hex could be is FF

00 - FF in hex works out to 0-255

Just put the actual number you want into any calculator that can do hex conversion. Calculator.exe that comes with windows can do this if you click "view" and change to "programmer".

 

The problem is it had to be transparent, but I found a solution, thanks anyway!
