"Reviewers mostly see Coolors as a fast, reliable way to generate harmonious color palettes and browse ideas, especially for design work, websites, apps, games, and even everyday styling. Several say it saves non-designers from guessing and has remained a go-to tool for years. The main criticism is not the core palette tool but the business layer around it: one reviewer says cancellation was mishandled, while another found the cookie banner, tutorial, and ads intrusive enough to limit classroom use despite calling the tool itself great."
