Normally the main workshop editor screen has the same color as ingame and the screenshot tab has the blueish inventory colors.
But right now the only way to use skins ingame is with a mod. any reason you cant use mods?

i mean that can i use skins in workshop?

You cannot use skins from the workshop unless overkill add it to a safe.
If you have the files yourself (that means if you made the skin) you can use a mod to use it ingame, no I wont link its easy to find

sorry for late reply, I cant mod the game cause if I try, I cant get into the game. It gonna force close immediately.. :(

The Payday 2 BLT requires a Windows computer running Windows 7 or later to work. You’ll also need the x86 version of the 2013 Visual C++ Runtime.

Had the same issue, in my case it was Vista.
