How to change shell tab color?

You can't as far as I've heard, as its hardcoded into the background program.

To be sure, you could look at the code, but I'm fairly certain that you'd have to make a modified version of it to change the colors.

But I 've seen it in OneOS …

After glancing at the multishell file, I found this:
(Starts at line 102)

-- Setup the main menu
local menuMainTextColor, menuMainBgColor, menuOtherTextColor, menuOtherBgColor
if parentTerm.isColor() then
    menuMainTextColor, menuMainBgColor = colors.yellow, colors.black
    menuOtherTextColor, menuOtherBgColor = colors.black, colors.gray
else
    menuMainTextColor, menuMainBgColor = colors.white, colors.black
    menuOtherTextColor, menuOtherBgColor = colors.black, colors.white
end

I don't think you can change it without modifying the program.

So you'll have to copy and paste this into a program of your own, and change the colors to your likeing.
You'll run that when you want to use multishell, instead of the default one.

They run a custom shell. If you copy /rom/programs/advanced/multishell you can edit that.

Or if you want something hacky, use this:

local oldSet = term.setForegroundColor
function term.setForegroundColor(color)
  if color == colors.yellow and select(2, pcall(error, "", 3)):match("multishell") then
	color == colors.red
  end
  oldSet(color)
end
