How do I fix this math.random() inside my game.Players.ChildAdded function?

So in the following code, the math.random() only prints out 5 every single time, so here's the code, and thank you for answering in advance.

view source
01game.Players.ChildAdded:connect(function(player)
02    local color = Instance.new("StringValue")
03    color.Name = "TorsoColor"
04    color.Parent = player
05 
06    local b = math.random(1,5)
07    print(b)
08 
09    if b == 1 then
10        color.Value = "Medium stone grey"
11    elseif b == 2 then
12        color.Value = "Dark Blue"
13    elseif b == 3 then
14        color.Value = "Maroon"
15    elseif b == 4 then
16        color.Value = "Earth green"
17    elseif b == 5 then
18        color.Value = "Brown"
19    end
20end)

That's because math.random() is not truly random. You will want to set math.randomseed() to a value that will be new or different each time the function is run. To accomplish this, you can set math.randomseed() to tick().

Tick is defined as:

Returns the number of seconds that have elapsed since the UNIX epoch (January 1st, 1970), on your computer.

Since time is constantly moving forward, tick() will give you a different value every time it is used. Therefore, it is a good value to set as math.randomseed().

It would look like this:

1math.randomseed(tick())

You would put this at the beginning of your function, so that is is called prior to math.random().
