Im making throttle notches where the ImageLabel changed using keys. Can anyone help me?

The problem im currently facing right now is that when I clicked the exact key, the gui color doesn't change as it needed. Here's the script:

local UserInputService = game:GetService("UserInputService")
local seat = script.Parent.Parent.Parent.Parent
local Players = game:GetService("Players")
local Notch1 = script.Parent["Notch+1"].ImageColor3
local Notch2 = script.Parent["Notch+2"].ImageColor3
local Notch3 = script.Parent["Notch+3"].ImageColor3
local Notchneutral = script.Parent.NotchNeutral.ImageColor3
local NotchN1 = script.Parent["Notch-1"].ImageColor3
local NotchN2 = script.Parent["Notch-2"].ImageColor3
local NotchN3 = script.Parent["Notch-3"].ImageColor3

Notchneutral = Color3.fromRGB(85, 170, 0)

UserInputService.InputBegan:connect(function(input)
	if input.KeyCode == Enum.KeyCode.W then -- Notch Neutral to Notch+1
		if Notchneutral == Color3.fromRGB(85, 170, 0) then
			Notch1 = Color3.fromRGB(85, 170, 0)
			Notchneutral = Color3.fromRGB(0, 0, 0)
		end
	end
	if input.KeyCode == Enum.KeyCode.W then -- Notch+1 to Notch+2

		end
	end

		end
	end
	if input.KeyCode == Enum.KeyCode.S then -- Notch+3 to Notch+2
		if Notch3 == Color3.fromRGB(85, 170, 0) then
