A London-based artist named Matt DesLauriers has developed a tool to generate color palettes from any text prompt, allowing someone to type in "beautiful sunset" and get a series of colors that matches a typical sunset scene, for example. Or you could get more abstract, finding colors that match "a sad and rainy Tuesday."
