problem with this script changing both TextColor?

When i press S, both the Continue and NewGame buttons turn white. but none of them turns back to the normal color, after you press W

what im trying to do is make a start screen gui that has a new game button and a continue button, that are selected with W (new game) or S(continue)

but when i press any button both of the text color turns white

local frame = game.Players.LocalPlayer.PlayerGui.ScreenGui.Frame.ImageLabel.Frame.Select


function onKeyPress(inputObject)
	if inputObject.KeyCode == Enum.KeyCode.W then
		print("W was pressed")
		if frame.Position == UDim2.new (0.5, 0,0.559, 0)  then
		frame.Position = UDim2.new(0.5, 0,0.5, 0) 
		script.Parent.Parent.Continue.TextColor3 = Color3.new(27, 42, 53)
			script.Parent.Parent.NewGame.TextColor3 = Color3.new(255,255,255)
			
			end
	
			
			elseif inputObject.KeyCode == Enum.KeyCode.S then
		print("S was pressed")
		if frame.Position == UDim2.new(0.5, 0,0.5, 0)  then
		 frame.Position = UDim2.new(0.5, 0,0.559, 0)  
		script.Parent.Parent.NewGame.TextColor3 = Color3.new(27, 42, 53)
			script.Parent.Parent.Continue.TextColor3 = Color3.new(255,255,255)
			
		end
	end
	end

			

		


 
game:GetService("UserInputService").InputBegan:connect(onKeyPress)

i also tried to put a changed function inside the button

local player = game.Players.LocalPlayer
local frame = player.PlayerGui.ScreenGui.Frame.ImageLabel.Frame.Frame
frame.Position.Changed:connect(function()
	if frame.Position == script.Parent.Position then
	script.Parent.TextColor3 = Color3.new(255,255,255)
end

end)

Output:

17:28:27.957 - Changed is not a valid member of UDim2
