We are currently working on building the design system for our web application. Please have a look at Ignitus Figma project to have a look at our progress.
The central principle of visual design in this app is the cleanness of user interface and the emphasis on the main elements of the content. Based on that was built look and feel of the app. For this purpose colors were defined as bold and engaging which can attract attention to an element even if it takes a small part on the screen. We also didn't want to confine our look into a limited choice of colors so it was decided to use many different shades for additional colors.
