A team of computer scientists and designers from the University of Waterloo has developed a ground-breaking tool called De-Stijl to assist people in using colour effectively in graphic design.
De-Stijl suggests intuitive colour palettes for novice designers and inexperienced users, leveraging powerful machine-learning technology. It combines and enhances the functionalities of existing tools like Figma, Pixlr, and Coolor, allowing users to select theme colours and visualise their impact on designs quickly.
The tool employs an innovative 2D colour palette, developed with input from expert graphic designers, which suggests colours and demonstrates their impact in different arrangements.
