Prompt Engineering for Vector Images

What is prompt engineering?

Check out part 1 where we discuss prompt engineering in general.

AI and vector images

In the realm of digital art and design, prompt engineering takes on a whole new dimension when it comes to vector images. The distinctive qualities and considerations associated with vector graphics present a world of possibilities for artists and designers seeking precise control over their creations. Let's explore what makes vector image prompt engineering a fascinating and distinct art form.

Vecor image prompting

When creating prompts for vector images, there are a few special considerations to keep in mind:

Keep things simple

When generating vector images we want to steer the AI towards simpler images. Generally vector images have clean lines, simple geometries and a limited number of colors.

For example:

  • "flat icon of a person baking a cake" (try it)
  • "a logo for an AI startup using 2 colors" (try it)

Geometric Shapes

Since vector images are based on mathematical equations and geometric shapes, you can be more explicit in your prompt about the specific shapes and their properties. For example, you can mention specific geometric shapes like circles, squares, or triangles, along with their sizes, positions, or orientations.

For example:

  • "Create a vector image with three concentric circles, each with a diameter of 10." (try it)
  • "Generate a vector illustration featuring a series of interlocking triangles, forming an abstract pattern." (try it)

Paths and Curves

Vector images often involve paths and curves that define the shape of objects. You can provide instructions related to the curvature, smoothness, or complexity of these paths. For instance, you can specify "smooth curves" or "intricate patterns of curves" to guide the generation of the vector image.

For example:

  • "Produce a vector graphic with smooth and flowing curves, resembling ocean waves." (try it)
  • "Design a vector image of a stylized bird, emphasizing the graceful curves of its wings." (try it)

Colors and Gradients

In vector images, colors and gradients can be defined using mathematical functions. You can be precise about the colors or color schemes you want, specifying RGB values, hex codes, or color names. Additionally, you can specify the direction and type of gradients, such as linear or radial gradients.

For example:

  • "Produce a vector image of a sunset with a gradient that transitions smoothly from warm oranges to cool purples." (try it)
  • "Create a vector illustration of a vibrant rainbow" (try it)


Vector graphics often involve layering and overlapping of different elements. You can provide instructions on the arrangement of objects, specifying which elements should be in the foreground or background. You can also guide the positioning and scaling of objects to create a desired composition.

For example:

  • "Generate a vector graphic of a landscape with overlapping layers of mountains, trees, and a flowing river." (try it)
  • "Design a vector illustration of a flower bouquet with petals overlapping in a natural and visually pleasing arrangement." (try it)

Precision and Scaling

Vector images are resolution-independent, which means they can be scaled to different sizes without loss of quality. Consider specifying the intended size or scale of the vector image in your prompt. For example, you might request a vector image suitable for a specific print size or a scalable logo design.

For example:

  • "Design a scalable vector logo suitable for both web and print, ensuring all elements maintain their clarity at different sizes." (try it)
  • "Generate a vector illustration of a city skyline that can be easily adapted for use in various promotional materials, from business cards to billboards." (try it)

Complexity and Detail

Vector images can range from simple geometric designs to intricate and detailed illustrations. Determine the level of complexity or detail you desire in the image and communicate that in your prompt. You can mention the level of intricacy or specify the amount of detail needed for certain elements.

For example:

  • "Generate a highly detailed vector illustration of a forest scene, with intricate tree branches, foliage, and wildlife." (try it)
  • "Design a vector graphic of a mandala with intricate patterns and geometric details, inspired by sacred geometry." (try it)
