"Design a distinctive logo for my Etsy shop brand 'Tumbler' highlighting our expertise in digital tumbler designs. Embrace a digital aesthetic by utilizing clean, sharp lines and a contemporary, digital-style font. Integrate a stylized tumbler silhouette to clearly convey our specialization. Infuse creative elements, such as a paintbrush or digital pen, to signify the artistic essence of our designs. Select a vibrant and attractive color palette that mirrors the diversity and vibrancy of our tumbler creations. Additionally, incorporate a subtle, personalized touch that pays homage to our brand name, 'Tumbler' through a signature-style font or a small, unique icon, butterfly."
