About fills and strokes

Last updated on Oct 27, 2025

Learn what fills and strokes are, and how they enhance the appearance of objects in Adobe Illustrator.

Illustrator provides two primary methods of painting:

  • Apply a Fill, a Stroke, or both to an entire object.
  • Convert the object to a Live Paint group and apply a Fill and a Stroke to the separate edges and faces of paths within it.

Fill

Fill is the interior color, gradient, or pattern inside an object. It adds visual weight, depth, and texture to vector shapes. You can apply a Fill to open and closed paths and faces of the Live Paint group.

There are three types of Fill:

  • Solid: Applies a uniform color evenly across the entire shape.
  • Gradient: Creates a gradual blend between two or more colors.
  • Pattern: Fills the shape with a repeating design or texture.

Stroke

A Stroke is the visible outline of a path or object. It defines the edge or contour and can complement or contrast with the Fill. You can apply Stroke to open and closed paths and edges of Live Paint groups. You can adjust the Weight, Cap, Corner, and Align Stroke to customize the Stroke.
