We have used the Color Switcher only for the demonstration purpose to show our template color versions. It’s not included in the main files, also Envato Market does not support to add Color Switcher in the main files.
Moreover, mainly the template will not work in a local computer or localhost. Because this template is based on Envato API and an API does not work without an online server.
Furthermore, you need to use your own Envato API key to get working with the template. Please check out steps from the provided documentation to work with the template.
