Mandate design refers to the architectural design of storefronts, and the term 'effect drawing in green' suggests a visual representation of the storefront using shades of green. Green in design can often convey a sense of nature, tranquility, or eco-friendliness. Storefront design effect drawings are typically used for presentations, marketing, and construction reference. They involve elements such as signage, lighting, materials, and architectural features to create an appealing and functional facade.
