Allow your users to finely tune the color theme of your application, software, or website. In this episode we will show how to save the user theme color choice as a cookie. In technical terms what we are doing is creating persisting data across sessions. Giving your application a data storage mechanism outside of itself, but yet tied to it. We will give the user controls in order to save their color theme and the color will automatically load for them in any of their future and subsequent visits to your application or website.
