Act as a seasoned graphic designer with 10+ years of experience in retro branding. Create a vibrant, nostalgic logo for a 1950s-inspired burger joint called [BURGER JOINT NAME]. The design should feature bold typography, a classic diner aesthetic, and playful elements like [CUSTOM ICON: e.g., a smiling burger, vintage car, or soda cup]. Use a color palette of [PRIMARY COLOR], [SECONDARY COLOR], and [ACCENT COLOR] to evoke retro charm. Ensure the logo is scalable for menus, signage, and merchandise. Include subtle textures like halftone dots or distressed edges for authenticity. The final output should feel timeless yet fresh, appealing to both older generations and modern foodies.
