i was scripting screenGui script that tracks speed by frames background color changing from white to yellow

and i dont think just copy paste if then elseif will be efficent way to make it

here is script

local Player = game:GetService("Players").LocalPlayer
local character = Player.Character or Player.CharacterAdded:Wait()
local humanoid = character:FindFirstChildOfClass("Humanoid")

local Gui = script.Parent
local SpeedGui = {
	Gui.P1,
	Gui.P2,
	Gui.P3,
	Gui.P4,
	Gui.P5
}

humanoid:GetPropertyChangedSignal("WalkSpeed"):Connect(function()
	local Speed = humanoid.WalkSpeed
	
	if Speed >= 20 then
		SpeedGui[1].BackgroundColor3 = Color3.fromRGB(255, 170, 0)
	else
		SpeedGui[1].BackgroundColor3 = Color3.fromRGB(255, 255, 255)
	end
end)

at very least it does detects if it reached that speed and does changes color from white to yellow and vice versa when speed is lower than needed

here what i came up

for i, v in pairs(SpeedGui) do
		if Speed >= 20 + (i * 5) then
			v.BackgroundColor3 = yellow
		else
			v.BackgroundColor3 = white
		end
	end

(dont bother about yellow or white i just shortened it)
