How do I change 'brickcolor' on value change?

I noticed that you have two objects inside of workspace called "adsyg". When you try to retrieve an object inside of a hierarchy it will return the first object of the name you give it. So if you try to do the whole "workspace.adsyg" twice, it will just return the same object twice.

In order to get both objects like you are trying to, you could either put the number value inside of the part or just change the name of the number value.

Another thing is on the first line when you declared value to be equal to workspace.adsyg.Value, since you're doing that any change to the number value after that will not be detected and the value variable will not change. This is because it's setting the variable to the value of the number value at that one time, it is probably in your interest to just get the number value object, and check the value when you need it.

Next, just a small syntax error on line 5 when comparing the value to a number. Just one equals sign "=" try's to set or declare something to be equal to another like a variable. What you want is a double equals sign "==" this compares two items together.

And finally just another small syntax error when setting the color of the parts. When setting the BrickColor it would be something like "part.BrickColor" and not "part.Color". When changing the color to a specific RGB value you can use "part.Color" with the Color3.fromRGB function.

Those were really the only problems I found with your code. Let me see if I can help fix it up for ya.

local part = workspace.adsyg --this is the part colour i want to change
local value = part.adsyg --this is my value thing (number value)

while true do
    local number = value.Value --the current value of the number value

    if number == 1 then
        part.BrickColor = BrickColor.new("Lime green")
    else
        part.BrickColor = BrickColor.new("Bright red")
    end

    wait()
end

All I'm assuming with this code is that you just put the number value object inside the part that changes color.

I hope I was helpful.

Use value == 1, not = 1.

I'm not entirely sure the difference between between them both but == should work.

Maybe someone with more knowledge can explain.

if value == 1 then

Something like this will work way better.

local part = workspace.adsyg

part.Value.Changed:connect(function(value)
    part.Color = BrickColor.new(value == 1 and "Lime green" or "Bright red")
end)

it will only fire if the value gets changed and you dont need to do a while loop
