I'm having trouble with a GUI changing colors of a TextLabel. Can someone help?

I have this GUI in my game that when it is clicked, it opens up a Frame that shows multiple clickable color boxes. The script is supposed to change the TextLabel color to the color the player clicked. I have been approaching it in different ways, but they all come out with a different outcome. Either the color boxes appear, and the clickable part doesn't work, or the color boxes don't appear at all. I would appreciate your help. Thank you.

Player 	= game.Players.LocalPlayer
--
RS 		= game:GetService("ReplicatedStorage")
GFiles	= RS:WaitForChild("GuiFiles")
Rank	= GFiles:WaitForChild("Rank")
Events	= RS:WaitForChild("Events")

ColorUI = script.Parent:WaitForChild("ColorUI")
ColorsBox = ColorUI:WaitForChild("Main"):WaitForChild("Colors")
ColorButton = script.Parent:WaitForChild("ChangeColor")

RankGui 	= nil
local open = false

while not game.Players.LocalPlayer do
	wait()
end
while not workspace:FindFirstChild(tostring(game.Players.LocalPlayer)) do
	wait()
end

-- The problem seems to be in the function LoadColors(), but it does not show any script errors. This function below makes the colors appear, and is supposed to change the TextColor of the TextLabel to the color the player clicks.
