The stroke color refers to the color of the outline or border of a shape or object in a design or artwork. It is essentially the color that defines the edges of a shape and gives it a distinct shape or form. The stroke color can be applied to various elements such as lines, curves, and text.



The fill color, on the other hand, pertains to the color that is applied to the inside of a shape or object. It is the color that occupies the area within the boundaries defined by the stroke color. The fill color can be used to add depth, dimension, and visual interest to a design or artwork.



1. Role:
The primary difference between stroke and fill color lies in their roles within a design or artwork. The stroke color defines the outline or border of a shape, while the fill color fills the interior area of the shape.

2. Appearance:
- Stroke color: The stroke color is visible as a line or border around the shape. It can have different thicknesses, patterns, or styles, such as dashed or dotted lines.
- Fill color: The fill color is visible within the boundaries of the shape, giving it a solid or patterned appearance. It can be opaque or transparent, allowing other elements to show through.

3. Manipulation:
- Stroke color: The stroke color can be adjusted to change the thickness or style of the outline, allowing for customization and emphasis on certain elements.
- Fill color: The fill color can be modified to alter the overall color scheme of a shape or object, creating contrast, harmony, or focal points within the design.

4. Purpose:
- Stroke color: The stroke color is often used to define the edges of shapes and objects, making them stand out and separate from the background or other elements.
- Fill color: The fill color is used to add visual interest, depth, and dimension to a design. It can be used to distinguish different areas or elements within a composition.



In summary, the stroke color defines the outline or border of a shape, while the fill color fills the interior area of the shape. They play different roles in the overall appearance and manipulation of design elements, contributing to the visual appeal and communication of ideas in a design or artwork.
