How to Write Vector Art Image Prompts - Nano Banana 2

That aesthetic is a legitimate target on its own, and it is one of the easier ones to hit, because it is defined by absence. Vector art is what you get when you remove texture, noise, soft shadows and rendered lighting.

The core clause is flat colour. Flat solid shapes, no gradients, no shading, no texture, no noise. Every one of those is a thing the model will add by default, and naming them as absent is more effective than hoping “vector” implies them.

Vector covers several distinct professional traditions, and naming one bundles a lot of decisions. Flat icon design means simple, centred, legible at small size, minimal detail. Corporate flat illustration means stylised figures with simplified faces and a limited brand palette. Mid-century modern vector work brings textured overlays, muted colours and geometric abstraction. Technical isometric illustration brings a fixed angle and precise construction.

These carry more information than any adjective. “Flat vector icon, single object, centred on a plain background” describes an entire genre of image in eight words.
