http://localhost:3000/users/new Routing Error

Im following this tutorial. http://ift.tt/1kmdoqc i just the part titled Adding Some Validations to the User Model

When i go to http://localhost:3000/users/new i get an routing error. But based on my knowledge the rout looks fine. Whats wrong?

user_controller.rb

class UsersController < ApplicationController
  def new
    @user = User.new
  end
  def create
    @user = User.new(params[:user])
    if @user.save
      flash[:notice] = "You signed up successfully"
      flash[:color]= "valid"
    else
      flash[:notice] = "Form is invalid"
      flash[:color]= "invalid"
    end
    render "new"
  end
end

routes.rb

Rails.application.routes.draw do
  get 'users/new'
