Particular emphasis is placed on using color theory, design theory, and user experience principles to create intuitive and effective user interfaces. In addition, it explores what attracts users the most and how the brain reacts to specific colors, shapes, and other visual elements. The result of this research is a product that allows its user to create their colour palettes, choose their layouts and typefaces for creating a design system. The implementation of all the gathered information is implemented as a website, with tools for web development, such as HTML/CSS, JavaScript, Angular, and Figma.20262026-03-13 11:55:02Diplomsko delo180676VisID: 63126COBISS_ID: 274399747sl
