My random color changer isn't working, why?

I'm trying to make it so when you join the game the textlabel will randomly change colors but when I test it, nothing happens and I get no errors. Why?

01local labelcolor = script.Parent.TextColor3
02 
03while true do
04    wait(.5)
05    local r = math.random(0,255)
06    local b = math.random(0,255)
07    local g = math.random(0,255)
08    labelcolor = Color3.fromRGB(r,g,b)
09    wait(.5)
10end

I'd try adding a dely above the Script, sometimes the Scriot can fun faster than the assets can load, it won't tell you it's nil Ziffixture 6913 — 6y

I see what you're trying to do. if the script is local, change the text color from the player gui instead of the native gui DeceptiveCaster 3761 — 6y

Wym? TypicallyPacific 61 — 6y

Please have a look at my answer. Thanks tonyv537 95 — 6y

When you do something like `local Variable = ValueObj.Value`, it's not defining the `Value` property, it's saving what the value is for the `Value` property; the simple solution's just to set the `.Value` each time you plan on doing it. (For example, TxtLbl.Color3 = Blah and no TxtLblColor3 = Blah) TheeDeathCaster 2368 — 6y

MCandRobloxUnited is doing it the long way around. Look at my answer. It works for me. tonyv537 95 — 6y

Hello,

This is one way you can randomly change the colour of the text button is by doing this. I will explain it in the script. I have done it with Color3, not Color3.fromRGB

FINAL SCRIPT USING Color3.new()

1-- Variables 
2local button = script.Parent
3 
4-- main bit
5 
6while true do -- this is an infinite loop
7    wait(1) -- do this or the game will crash due to overloading
8    button.TextColor3 = Color3.new((math.random()), (math.random()),( math.random())) -- the reason that the brackets have been left blank will be explained
9end

So, leaving the brackets blank means that the values that themath.random() function will return is a decimal between 0 and 1 I printed math.random() and this was the output

54552773666264
2989054301143
084517205494783
24972764937719
90271937913953
86965136187734

and the values for Color3 have to be a number between 0 and 1, and math.random() will fetch you a multitude of decimals between 0 and 1.

If this helped, please accept it. Thanks!

you also forgot that the Roblox color spectrum uses numbers that are integers not decimals DeceptiveCaster 3761 — 6y

And you clearly don't know that TextColor3 uses a number between 0 and 1. https://developer.roblox.com/api-reference/property/TextBox/TextColor3 . According to your logic, tell me a number between 0 and 1 that is an integer. tonyv537 95 — 6y

Maybe try this in a local script and this script instead?

01local labelcolor = script.Parent.TextColor3
02 
03while wait(1) do
04 
05    local r = math.random(0,255)
06    local b = math.random(0,255)
07    local g = math.random(0,255)
08    labelcolor = Color3.fromRGB(r,g,b)
09 
10end

wrong. you can't change the gui that way and while wait() do is deprecated. DeceptiveCaster 3761 — 6y
