How to change Brick Color with a script?

local Parent = script.Parent

local ChangeColor = Parent.BrickColor

local intValue = game.Workspace.Value

if intValue == 1 then 
	ChangeColor = BrickColor.new("Gold")
	if intValue == 0 then 
		ChangeColor = BrickColor.new("Dark Blue")	
	end
end

For some reason this won't work? And it has no output error?

You need to do it like this, when you want to change a property of an object, never set a variable to local x = object.someproperty, instead use local x = object Then when you need to change that value, use x.Property = whatever.

local ChangeColor = script.Parent;

local intValue = game.Workspace.Value

if intValue == 1 then 
    ChangeColor.BrickColor= BrickColor.new("Gold")
    if intValue == 0 then 
        ChangeColor.BrickColor = BrickColor.new("Dark Blue")   
    end
end
