Ability to change color scheme

[chavda-bhavik]

Current Scenario

The upload Widget Looks as follows when clicking on the Import button,

where blue is the primary color, which may not be preferable for every project.

Proposal

We can implement the facility to change the widget's primary color so that it gets matches the application's primary color. 😃

Ways to bring it forward

1. Provide primary color to the React component, and that primary color will reflect on the widget. More convenient for an application that allows users to change the theme color.
2. Prive primary color in the Project/Template entity and that color will get reflected on the widget.

Any thoughts or suggestions?
